What is the phenomenon of rainbow formation?

• Scattering of moonlight by water droplets

• Reflection of sunlight by clouds

• Absorption of sunlight by water droplets

• Refraction, reflection, and dispersion of sunlight by water droplets

What is absorption of light?

• The process in which light is emitted by an object

• The process in which light is converted into sound

• The process in which light is taken in by an object, rather than being reflected or transmitted.

• The process in which light is completely blocked by an object
