Question

Assertion(A): Secondary rainbow is fainter than primary rainbow
Reason(R): Secondary rainbow formation is three step process and hence, the intensity of light is reduced at the second reflection inside the rain drop

1.Both A and R are true and R is the correct explanation of A

2.Both A and R are true and R is NOT the correct explanation of A

3.A is true but R is false

4. R is true but A is false​

Answer 1

answer:--

the additional reflection, the colors in the secondary rainbow are reversed in order compared to the primary rainbow. Since some light is lost out of the raindrop with every reflection, the secondary rainbow is much fainter than the primary rainbow.

hope it helps you ❤️

Answer 2

1. Both A and R are true and R is the correct explanation of A

Explanation:

The secondary rainbow appears outside the primary rainbow and occurs when the light entering the raindrop experiences two internal reflections instead of just one (as in the case of the primary rainbow). The secondary rainbow is not as bright as the primary rainbow because the light intensity is further reduced by the second reflection.

When the ray reflects twice in the drop, a second rainbow is created. Therefore, its formation is a four-step process of refraction, reflection, reflection, and refraction.

The outermost color of the secondary rainbow is purple and the innermost color is red. These rainbows are dimmer than the primary rainbow because a small number of rays experience two internal reflections in the raindrops.
