Explanation of mirage in terms of physics

It is the refraction and total reflection of light.

It is an upright virtual image.

It is a phenomenon of refraction of light!

First of all, your question is wrong.

The imaginary images are upright.

The reality is all upside down.

A mirage is a refraction of light.

<>1. Mirage is an optical illusion, which is the refraction and reflection of light.

2. The mirage is the reflection of the distant building or landscape, the reason is that when the sun shines on the surface, the ground temperature rises, and its density becomes smaller, and the temperature above the ground is relatively low, the density is larger, when the light rays from the dense air layer into the low density gas layer, its angle deviates, people can see the distant landscape according to the light, that is, the mirage. According to the angle of refraction of light, it can be divided into upper mirage, lower mirage and lateral mirage. The phenomenon of mirage often occurs in areas with large temperature differences or high gas densities.

Mirage is a phenomenon that mostly occurs in deserts and seas.

According to the principles of physics, a mirage is due to the fact that different air layers have different densities, and light has different refractive indices in different densities of air.

Understand: The refraction of light, like the reflection of light, occurs at the junction of two media, except that the reflected light returns to the original medium, while the refracted light enters the other medium. Since light travels at different speeds in two different substances, the direction of propagation changes at the junction of the two mediums, which is the refraction of light.

Mirage has two characteristics:

One is repeated in the same location, such as the mirage over Alaska in the United States; For example, most of the mirages in Penglai in China appear in the month of each year, the mirages near Zimlensk in Russia often appear in spring, and the mirages in Alaska in the United States generally appear within 20 days after June 20.

A "mirage" that occurs in the desert is a phenomenon in which sunlight meets air of different densities and refracts. In the desert, the sand and gravel are scorched by the sun during the day, and the temperature on the surface of the sand layer rises rapidly. Due to the poor heat transfer performance of the air, when there is no wind, the vertical air temperature difference over the desert is very significant, the lower is hot and the upper is cold, the upper air density is high, and the lower air density is low.

When sunlight enters the denser layer of air from the denser layer of air into the less dense layer of air, the angle of light changes, and the light is refracted to reveal the distant oasis in front of people's eyes. On the surface of the sea or river, this phenomenon of "mirage" sometimes occurs.

A mirage is a natural phenomenon formed by the refraction and total reflection of light.

When the meteorological conditions and geographical location are suitable, there will be an illusion formed by the refraction of distant objects, and people will see the image of the actual landscape in the sky, which is called a mirage. This phenomenon can be repeated in one place.

Specifically, a gradient of air temperature formed by the sun raising the temperature of the ground. Due to the different densities, light rays are refracted at the temperature gradient demarcation. Our brains think that light always travels in a straight line, but when light rays pass through the cooler, denser atmosphere below, they are refracted downward, so we see distant objects higher than they actually are.

The mirage is due to the refraction of light.

Since the density of the air near the surface varies due to different temperatures, light passes through the air of different densities and is refracted by it. When the conditions are met, distant scenery forms a mirage.

A mirage is a physical phenomenon of refraction of light and reflection of the limbs. A mirage, also known as a mirage, is a natural phenomenon formed by the refraction and total reflection of light. Its formation is closely related to the weather situation, meteorological conditions, geographical location, geophysics, etc.

Only the mirage can be seen on the sea or on land. It is characterized by repetition in the same place and at the same time. Due to the different densities, light rays are refracted at the temperature gradient demarcation.

The human brain thinks that light always travels in a straight line, but when the light passes through the cool, dense atmosphere below, it will refract downward, so the distant tall buildings that appear in the brain will be taller than they actually are.
