Question

what is
mirage?explain the conditions under which it is seen

Answer 1

Answer:-

Mirage is an optical illusion caused by the phenomenon of total internal reflection of light. Mirage happens in a hot sunny day creating an illusion of water. but when we reach there, nothing seems to be there. On a hot day earths temperature on surface increases. This led to heating up of air surrounding them. But the air present in the atmosphere will be cooler. Scientifically speaking refractive index of hot air is lesser than cold air. So when a light pass from cold air to hot air light tends to bend which is known as refraction. As the light get refracted it reaches to a point where the light tends to form 90degree angle. No more refraction takes place when it reaches 90, besides all the light get reflected back. At this point of time trees look inverted which looks as if it is inverted on a pool. So this is total internal reflection. Mirage is observed due to this.
