How mirage is formed?
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.
Is Arcturus mentioned in the Bible?

What is Amirage?
A mirage is a phenomenon where you think you see water. In this picture it looks as though these mountains are reflected in a lake. There might not even be mountains there at all. Mirages are most common in deserts. They happen when light passes through two layers of air with different temperatures.
What is Mirach used for?
