What is the phenomenon of light through which the mirage is formed, and what is the detailed process

<>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.

It's refraction.

Due to the uneven heating of the air, the density of the air parts is different, so the light is refracted when it travels through the air.

Mirages are often produced at sea and in the desert. A mirage is the result of the refraction of light rays in layers of air with different densities in a straight line.

Air itself is not a homogeneous medium. In general, its density decreases with increasing height. The higher the height, the lower the density. When light passes through the air at different heights, it always causes some refraction.

A mirage is a naturally occurring optical phenomenon in which light rays are bent to create a moving image of a distant object or sky. The word comes from France, and Latin means miracle. It's the same as a "mirror".

Mirages can be divided into submirage mirages, and lateral mirages.

A high-level mirage composed of an unusually complex series of vertically stacked images, forming a rapidly changing phantom.

In contrast to hallucinations, a mirage is a real optical phenomenon that can be captured on glasses and cameras, because in fact the light rays are refracted and form an illusion at the observer's position.

However, what the image seems to represent is determined by the explanatory power of the human mind. For example, poor quality images on land can easily be mistaken for reflections from small bodies of water.

AlthoughThe temperature of the atmosphere depends on the density of the air, when the temperature increases or decreases from low altitude to upward, and when there are 3 patterns, the horizontal temperature changes。Since the appearance of apparitions is different from each one, they are classified as follows. It is divided into upper mirage, lower mirage, and lateral mirage.

A higher mirage occurs when the air below the line of sight is colder than the air above it。This unusual arrangement is known as temperature inversion because the warm air above the cold air is the opposite of the normal temperature gradient of the atmosphere. By temperature reversal, the light is bent downward, so the image appears above the real object, hence the name mirage.

Upper mirages are quite long and less clear than lower mirages, however, when they do occur, they tend to be more stable and do not dissipate easily. Because there is no upward trend in cold air and no downward trend in warm air.

In polar regions, especially on large sheets of ice with uniform low temperatures, clear mirages are very common. Better mirages also occur at latitudes with milder temperatures, although in these cases they are weaker and tend to be less smooth and stable. For example, a lighthouse may appear on a distant coastline and slowly rise or slowly approach, indeed.

Due to the turbulence, there seem to be dancing pinnacles and towers. This type of mirage is also known as Fata Morgana.

Depending on the distance and temperature gradient of the real object, the lateral mirage can be upside down on the right side. Typically, the image appears as a twisted blend of upper and lower parts.

Due to the curvature of the Earth, a mirage can produce amazing effects. Due to the flat surface, the bent light will quickly hit the ground, and only nearby objects will be affected. The second point is that since the Earth is round, if their downward curve curves are about the same as the curvature of the Earth, then the rays may travel a great distance, perhaps from beyond the horizon.

Many times, UFO UFOs that people find are partly fantasies created by mirages.

To see a mirage, you need to understand the reasons for his formation plus luck.

What exactly is a mirage? Science gives you the perfect explanation.

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.

Mirages can be seen at 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 brain thinks that light always travels in a straight line, but when light passes through the cool, dense atmosphere below, it refracts downward, so that distant buildings appear in the brain are taller than they actually are.

The formation of a mirage is closely related to the weather situation, meteorological conditions, geographical location, geophysics, etc. When a mirage appears, there is a noticeable change in the weather.

According to the analysis of the data, the day before the appearance of the "mirage", there was significant precipitation and cooling weather, and the temperature was generally significantly lower than the previous day.

"Mirages" often occur at sea, because the air humidity and thickness of the space within a certain range of the sea are relatively large, so that the large area of water vapor under the movement of the air inadvertently forms a huge lens system. When the temperature near the ground changes drastically, it will cause a huge difference in the density of the atmosphere, and the distant scenery will undergo abnormal refraction and total reflection when the light propagation, resulting in a mirage.

In addition, the occurrence of "mirage" is also related to the refractive index of the air layer at different altitudes, and the content of water vapor is an important meteorological factor that directly affects the refractive index. At the same time, there is also a certain relationship with the sudden change of temperature and relative humidity.

The air near the surface of the sea has a higher refractive index due to the lower sea temperature and moist water vapour, while the air above is warmer due to the influence of sunlight.

The refractive index of the air layer above the sea surface gradually decreases with the height from bottom to top, due to the discontinuity of the change of meteorological elements, the refractive index change of light in the air also shows discontinuity, when the light passes through the air layer top with a large refractive index, it is easy to form total reflection under the meteorological conditions of clear, windless or breeze, thus producing the wonder of "mirage".

A mirage is a phenomenon of refraction of light. Refraction of light refers to the change in the direction of propagation of light when it hits obliquely from one medium to another, causing the light to deflect at the junction of different media.

A mirage is an illusion formed by the refraction of distant objects, resulting from a temperature gradient formed by the sun raising the temperature of the ground. Due to the different densities, the light rays will refract at the boundary of the temperature gradient. Our brain thinks that light always travels in a straight line, but when light rays pass through the cool, dense atmosphere below, they are refracted downward, so distant objects appear higher in the brain than they actually are.

"Mirages" often occur at sea, because the air humidity and thickness of the space within a certain range of the sea are relatively large, so that the large area of water vapor under the movement of the air inadvertently forms a huge lens system. When the temperature near the ground changes drastically, it will cause a huge difference in the density of the atmosphere, and the distant scenery will undergo abnormal refraction and total reflection when the light propagation, thus causing a mirage.

When light is obliquely transmitted from one medium to another, the direction of propagation changes, causing the light to deflect at the junction of different media. Refracted rays and incident rays are separated on either side of the normal. Refracted rays, incident rays, and normals are in the same plane.

Under the same conditions, the angle of refraction increases (decreases) as the angle of incidence increases (decreases). When light is emitted vertically from the air into water or other media, the direction of propagation of the ridge does not change.

Resolution

A beautiful and peculiar "mirage" is a phenomenon created by the refraction of light through small droplets of water in the air. It usually occurs during the summer months. Because the temperature is very high in summer, different air layers have different densities, and light has different refractive indices in different densities of air, and the density between the warm air on the road surface and the cold air in the upper air is different, so the light will be refracted on the road surface;

The light of distant objects travels through the air on the road surface, and after refraction, it enters the human eye, and people always see a virtual image higher than the actual position of the object because they always think that the light travels in a straight line. This is the principle of "mirage". Therefore, it usually occurs in the summer.
