Question

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

Answer 1

Answer:

option d is correct answer

Answer 2

While entering a water droplet, the sunlight gets (d) First refracted then dispersed while coming out of the water droplet.

• When sunlight enters water droplets suspended in the air, rays undergo refraction since air is optically rarer than water.
• The rays get bend towards the normal as they travel across the droplet.
• Sunlight is white light i.e. it is composed of 7 different EMW of different wavelengths. During dispersion, these components get separated and we see a spectrum.
• This phenomenon is also responsible for the formation of a rainbow.
