Mirages are observed on some days when
1)Density of air increases with height
2)density of air decreases with height
3)earth acts like a mirror
4)air is dense uniformly
for a mirage to occur... a light ray must go from denser to rarer medium and undergo Total internal reflection.. and here the air near the ground. which is hot, is rarer..
and density increases upwards.
so option 1 is correct
