Question

Which of the following statement is correct ?

• A. In primary rainbow, observer sees red colour on the top and violet on the bottom
• B. In primary rainbow, observer sees violet colour on the top and red on the bottom
• C. In primary rainbow, light wave suffers total internal reflection twice before coming out of water drops
• D. Primary rainbow is less bright than secondary rainbow.

Answer 1

Answer: (A)

In primary rainbow, observer sees red colour on the top and violet on the bottom

Answer 2

The correct statement is:

"In primary rainbow, observer sees red colour on the top and violet on the bottom."

This is because red light is refracted less than violet light, causing red to appear on the outer part of the rainbow and violet on the inner part. The other statements are not accurate descriptions of primary rainbows.

So, the correct option is (A).
