When a mirage appears, what will you see when you fly a fighter plane to a mirage?

Mirages usually appear in relatively dry deserts. If you meet a mirage, what will you see when you fly to a mirage with a fighter plane? A mirage is just a shadow, and it doesn't really exist. So when we fly by combat plane, the effect is the same as when we go there by ourselves, and we know the formation conditions of mirage. Mirages often appear in coastal areas and occasionally can be seen in the desert. In fact, this is a self-defense that modern science cannot explain.

The light that people can see is in the visible range (400-700 nanometers). We see matter because our eyes can receive visible light reflected by matter. When you insert a straight rod obliquely into the water, you can see that the underwater part of the rod and its exposed part seem to be broken, which is the result of light refraction. Someone once used a device like the one on the left to project light from water to the interface between water and air. You can see that light is divided into two parts at this interface: one part is reflected into water and the other part is refracted into air.

If the mirror in the water is rotated to make the light incident on the interface more inclined, then the refraction of light in the air will be more intense. When the light incident on the interface is shown in the figure on the left, all the light is reflected into the water, and no light is refracted into the air. This light is called reflection. The abnormal distribution of temperature is the meteorological condition for the formation of most mirage. As far as the formation of taking down the slug is concerned.

In summer, when the sun burns in the desert, the sand is burnt. Because of the small specific heat of sand, the temperature of low-level air near sand rises rapidly, while the temperature of high-level air is still very low, thus forming an abnormal distribution of temperature. Due to thermal expansion and contraction, the density of hot air in the lower layer near the sand is small, and the density of cold air in the upper layer is large, so that the refractive index of air is small and the air in the upper layer is large. When the light reflected by a distant higher object enters the sparse air in the lower layer from the dense air in the upper layer, it is constantly refracted, and its incident angle gradually increases, which is equal to the critical angle, and total reflection occurs. At this time, if people look against the reflected light, they will see the cockroaches below. However, a mirage is a kind of immaterial existence, and we can't see it when we get close.
