Why is the Sun s rays stronger than usual during a solar eclipse?

During a solar eclipse, the sun's rays are not stronger than usual, they should be weaker.

Usually the sun is very strong, which will burn the naked eye, but we don't look directly for a long time, because it is too dazzling! The eclipse is different, our eyes feel not very bright, especially when the eclipse area is relatively large, there will be no dazzling feeling when looking directly for a long time, so that we can look directly for a long time, but at this time the sun's rays still reach the intensity of burning the eyes, so only we emphasize that "the eclipse can not be directly naked eye**"!

In fact, we shouldn't look directly at the sun for a long time.

You must not look at the sun with a telescope! The telescope can bring the distant magnification closer, and the light-emitting object is equivalent to focusing, and the focused sunlight is both bright and hot, shining on our retina, of course, burning the retina instantly!

The intensity of sunlight filtered by sunglasses is still not lower than the intensity of direct visible light!

Normally, there should be no reason for this, I believe that it is because the sun is so bright that we will not force ourselves to look at it directly, but there is no way to do it in a solar eclipse, and if you have to look at it hard, you will feel very tired in your eyes.

I didn't realize it was happening before, during, or after.

What does the book say?

Is there a connection between what the book says and what you say? Is it true that you can usually look with sunglasses, but you can't when the sun is eclipsed?

In fact, the situation is the same as during the solar eclipse, and you can't look directly with sunglasses. The safe kind. Can you usually use sunglasses to look casually?

Maybe it's like the water suddenly encounters a narrow pipe.

It's not stronger than usual, what does the book say? It's certainly not that the light is stronger than usual.

It's useless to wear sunglasses when watching the sun, and you have to use appropriate light reduction measures. Or is it cloudy when LZ usually looks at the sun? It was a little weaker. I don't believe that LZ uses the same method to observe the sun on a sunny day, and it is definitely brighter than during a solar eclipse.

In addition, there is a convex lens in the telescope, so it is not possible to look directly at the sun through the telescope with the naked eye, no matter what time of the day. Burned ants with a magnifying glass, right? That's it. If you want to see the sun with a telescope, you must install a professional filter and install it on the mirror port.

A solar eclipse is a phenomenon of linear propagation produced by light.

Solar and lunar eclipses are typical examples of light propagating in a straight line in the same homogeneous medium. It is not every time a solar eclipse occurs when the moon moves between the sun and the earth, and two conditions need to be met for a solar eclipse to occur. First, solar eclipses always occur on New Year's Day (the first day of the lunar calendar).

Eclipses are not guaranteed on all New Moons, because the Moon's orbit (the white path) and the Earth's orbit (the ecliptic) are not in the same plane. The plane of the white and the plane of the ecliptic have an angle of 5°9. Second, both the Sun and the Moon move near the intersection of the white and ecliptic paths, and the Sun is at a certain angle from the intersection (eclipse limit).

Since the orbits of the Moon and the Earth are not perfectly circular, and the distance between the Sun and the Moon and the Earth is sometimes near and far, the shadow formed by the sun's rays being obscured by the Moon can be divided into umbra, pseudoumbra (formed when the Moon is far away from the Earth) and penumbra on the Earth. The observer is in the umbra range and can see a total solar eclipse; An annular solar eclipse can be seen in the pseudoumbra range; In the penumbra range, only a partial solar eclipse can be seen.

The law of light propagation.

Light travels in a straight line (in a homogeneous medium), but when the light meets another medium (homogeneous medium), the direction changes, and it still travels in a straight line. Whereas, in a non-homogeneous medium, light generally travels in a curve. The propagation path of the above light can be determined by Fermat's principle.

When the brightness of the light is darker, the light from the luminaire to the illumination reference object will expand, the farther the distance, the greater the diffusion, from the initial shape to the disappearance, and when the luminous body is zero distance from the illumination reference object, the shape of the light is the real shape size of the luminous body, so the direction of light propagation is related to the brightness of the light and the distance between the light and the illumination reference object.

A solar eclipse is a phenomenon in which light travels in a straight line.

The moon moves between the sun and the earth, and if the three are exactly in a straight line, the moon will block the sun's light from the earth, and the dark shadow behind the moon will fall on the earth, and a solar eclipse will occur. People in the shadow of the moon on Earth began to see the sunlight gradually weakening, the sun surface was obscured by a round black shadow, and when the sky turned dark, the brightest stars and planets could be seen in the sky.

A few minutes later, sunlight gradually emerged from the edge of the moon's dark shadow, and began to glow and recircle. Since the Moon is smaller than the Earth, only people in the shadow of the Moon can see the eclipse.

Laws of Solar Eclipse Occurrence:

There are up to 5 solar eclipses per year, and if they occur 5 times, then they must be partial eclipses. There are at least 2 solar eclipses per year on Earth. Only partial solar eclipses can be seen in the Arctic and Antarctic regions.

A total solar eclipse occurs about once every 1 1/2 years. Each eclipse begins at a certain point at sunrise and ends at sunset along the eclipse belt. It is about half a circle around the earth from the start point to the end point.

The eclipse must have occurred on the first day of the lunar calendar. When a solar eclipse occurs, both the Sun and the Moon must occur near the "yellow and white nodes" (ascending or descending nodes).

After a solar eclipse there will be tidal changes that affect the oceans and atmosphere, as well as the weather conditions of the Earth. It will happen that the solar wind will rush directly to the ground, and the solar wind will be more divergent. The solar eclipse is also followed by a magnetic field.

1. After the solar eclipse, there will be tidal phenomena that affect the oceans and atmosphere, as well as the weather conditions of the earth<>

Solar eclipses are just astronomical phenomena for most people, but it is different for the earth, and there will be tidal phenomena after the eclipse, although there is no actual harm, but there are still some small effects, first of all, we know that when the moon runs to the middle distance between the sun and the earth, the light of the sun's rays hitting the earth will be blocked by the moon, then we will see a black shadow next to the sun slowly gliding past, this is the solar eclipse. The moon for us can make the night no longer so dark, can see the surrounding things clearly, but not only to let human beings see the things around clearly, the second often affects the earth's tidal activity, tides are very important for the earth's sea, if there are no tides, the sea movement will become extremely slow, thus affecting the survival of fish life in the ocean, the moon will also affect the atmosphere, resulting in the weather that affects the earth.

Second, it will happen that the solar wind will rush directly to the ground, and the solar wind will be more divergent <>

The sun is not only hot, but also emits the solar wind, the earth's atmosphere is to filter the solar wind, if there is no solar wind, the consequences are hard to imagine, the solar wind is a charged plasma charged particle group, so it will affect the electronic equipment on the ground, this effect is self-evident.

3. After the solar eclipse, there will also be a magnetic field phenomenon <>

The atmosphere is only one of the ways to protect the earth, there is also the earth's magnetic field, the earth's magnetic field can also protect the earth, when the solar wind blows to the earth, the first one protects the atmosphere, then the second is the earth's magnetic field, without these natural conditions to protect the earth, it is difficult for the earth's creatures to survive, so we must protect the earth.

At that time, you will find that your sky is very bright, and there will be a very bright scene in the sky, and there will be a change in a large constellation, which is very powerful.

There will be two noticeable phenomena after the eclipse, firstly, the decrease in the visibility of the Earth, as if we live at night, and secondly, the temperature of the Earth will of course drop, which is most noticeable in the desert!

Most solar eclipses are followed by tidal changes, and the ocean atmosphere is affected to varying degrees.

The most obvious phenomenon is that the sky is dark, because at this time the sun can be completely obscured, leaving only a golden arc.

The reason why the sun in a solar eclipse feels round and dazzling is that when a solar eclipse occurs, the overall ambient light becomes darker, which highlights that the sun becomes very dazzling, but in fact, it is not the sun that becomes dazzling, but the noisy surrounding environment becomes darker.

Solar eclipses are formed based on the linear propagation of light. It occurs when the central part of the sun is dark and the edges are still bright, forming a halo. This is because the Moon is between the Sun and the Earth, but it is far away from the Earth and cannot completely cover the Sun.

Solar eclipse is a phenomenon of linear propagation of light, solar eclipse, also known as solar eclipse, is the movement of the moon to the middle of the sun and the earth, if the three are exactly in a straight line, the moon with the stove ball will block the light of the sun to the earth, and the black shadow behind the moon just falls on the earth, and the solar eclipse phenomenon occurs.

The Sun is the central body of the solar system and occupies the overall mass of the solar system. The eight planets, asteroids, meteors, comets, outer Neptune objects, and interstellar dust in the solar system all revolve around the Sun, while the Solar Segment revolves around the center of the Milky Way.

A solar eclipse is a phenomenon in which light travels in a straight line.

A solar eclipse is also known as a solar eclipse, the phenomenon of a solar eclipse is actually the movement of the moon between the sun and the earth, when the three are exactly in a straight line, the moon will block the light of the sun to the earth, and the shadow behind the moon just happens to fall on the earth, which occurs the phenomenon of solar eclipse.

Solar eclipses occur only when the Moon and the Sun coincide, and can be divided into partial solar eclipses, total solar eclipses, annular solar eclipses, and total annular eclipses. However, during a solar eclipse, you should not look directly at the sun, otherwise it will cause blindness to the eyes to varying degrees.

1. A total solar eclipse is a linear propagation phenomenon produced by light.

2. A solar eclipse is also known as a solar eclipse, and the solar eclipse phenomenon is actually that the moon moves between the sun and the earth, when the three are exactly in a straight line, the moon will block the sun's light from the earth, and the shadow of the moon behind the moon just happened to fall on the earth, which collapsed and there was a solar eclipse.

A total solar eclipse is a phenomenon of linear propagation produced by light. It is best to use "eclipse glasses" to observe total solar eclipse, professional eclipse glasses mostly use polyester plastic high-density composite film covered with double or multi-layer aluminum film, the transmittance of visible light is below, and after various wavelengths of light transmittance detection, it can filter out the powerful ultraviolet and infrared rays to the greatest extent. If you don't have eclipse glasses, you can use a welder to burn the glasses you wear when you weld instead.

A solar eclipse is when the moon circles the earth and turns between the sun and the earth, if the sun, the moon, and the earth are exactly lined up or close to a straight line, the moon blocks the sunlight that shoots to the earth, and the black shadow behind the moon falls on the earth, and the solar eclipse phenomenon occurs.

People in the shadow of the moon on the earth began to see the sun gradually weakening, the sun surface was obscured by a round black shadow, when the sky turned dark, all the brightest stars and planets could be seen in the sky, and after a few minutes, the sun gradually appeared from the edge of the moon's black shadow, and began to produce light and recircle.

Since the Moon is smaller than the Earth, only people in the shadow of the Moon can see the eclipse. A total solar eclipse occurs when the Moon blocks all the sun, a partial solar eclipse occurs when part of the sun is occluded, and an annular solar eclipse occurs when part of the sun is occluded. A total solar eclipse lasts no more than 7 minutes and 31 seconds.

The maximum length of an annular solar eclipse is 12 minutes and 24 seconds. China has the oldest record of solar eclipses in the world, and there have been definite records of solar eclipses more than 1,000 years BC.
