Explain the formation of a mirage.
want a detailed answer...
Answers
Answer:
Mirages happen when the ground is very hot and the air is cool. The hot ground warms a layer of air just above the ground. When the light moves through the cold air and into the layer of hot air it is refracted (bent). A layer of very warm air near the ground refracts the light from the sky nearly into a U-shaped bend.
Answer:
Mirage is an optical phenomenon which creates an illusion of the presence of water and is a result of refraction of light from a non-uniform medium. Mirage is observed mainly during sunny days when driving on a roadway.
How is it caused?
Mirage is caused due to total Internal Reflection of light by the various layers of air. It is an optical illusion which is responsible for the appearance of the water layer at short distances in a desert or on the road. Mirage is an example of total internal reflection which occurs due to atmospheric refraction.
Explanation:
When the light rays from the sun travel straight through the atmosphere, these light rays travel at different speeds through the hot and cold air. For mirage to occur the ground should be very hot and the surrounding air cold. The layer which is above the ground gets warmed. The light ray gets refracted when the light moves through the cold air and into the hot air layer. This is how mirage occurs.
