Question

60 , While entering a water droplet the sunlight gets : Refracted only (b) Reflected internally (c) Refracted and dispersed (d) First refracted and then dispersed while coming out of the water droplet​

Answer 1

Answer:

Option (d) - First refracted and then dispersed while coming out of the water droplet​.

Explanation:

When sunlight enters a water droplet, it is entering from a rarer medium to a denser medium, ie; from air to water. So the rays will undergo refraction at the boundary itself. Once the light has entered the droplet it will undergo dispersion. The dispersed light will then have to suffer total internal reflection inside the droplet. After that, the dispersed light ray will be refracted out of the droplet forming the rainbow.

Answer 2

Answer:

Option d) First refracted and then dispersed while coming out of the water droplet​
