Question

During hot summer days, we observe the air above land to be shimmering why

Answer 1

Here is the answer for your question..



If we pass through a farmland during a hot summer day, we will see that the aire above the soil is shimmering(shining with slightly shaking light). This happens as follows: The soil in the farmland contains some water.On a hot summer day, this water of soil evaporates to form water vapour.The water vapour coming out of the soil reflects the sunlight irregularly due to which the air above the soil seems to shimmer.

Hope it helps....
