In a primary rainbow red colour is on outermost arc, violet is in innermost arc. The red rays appear to be coming from a water droplet which subtends 42∘ to the eyes whereas violet rays appear to be coming from a water droplet which subtends 40∘ to the eyes. that's why answer is 'A'

Which of the following statements is correct about rainbow ?a)In prima...
The correct statement about a rainbow is option A: In a primary rainbow, red color is on the outside and violet color is on the inside.
Explanation:
A rainbow is an optical phenomenon that occurs when sunlight is refracted, or bent, as it passes through water droplets in the air. This bending of light causes the different colors of the spectrum to separate and form a circular arc of colors in the sky.
1. Primary Rainbow:
- A primary rainbow is the most common type of rainbow that we observe.
- It is formed when sunlight is refracted, reflected, and then refracted again inside a water droplet before exiting.
- The light undergoes two refractions and one reflection inside the droplet.
- The primary rainbow appears as a semicircular arc, with red color on the outside (top) and violet color on the inside (bottom).
- This arrangement is due to the different angles at which the different colors of light are refracted and reflected inside the droplet.
- Red light is refracted the least, while violet light is refracted the most.
- As a result, red light exits the droplet at a steeper angle than violet light, causing the red color to be observed on the outer edge of the rainbow and the violet color on the inner edge.
2. Secondary Rainbow:
- A secondary rainbow is less commonly observed and appears as a larger arc outside the primary rainbow.
- It is formed by a more complex process involving two reflections and one refraction inside the water droplet.
- In a secondary rainbow, the light undergoes two reflections inside the droplet before exiting.
- The secondary rainbow is dimmer and has its colors reversed compared to the primary rainbow.
- The violet color is on the outside (top) and the red color is on the inside (bottom) of the secondary rainbow.
- This reversal occurs because the light undergoes an additional reflection inside the droplet, causing the colors to be reflected and refracted in the opposite order.
- The secondary rainbow is also located at a larger angle from the center of the rainbow compared to the primary rainbow.
Therefore, the correct statement is option A: In a primary rainbow, red color is on the outside and violet color is on the inside.
