Optical Instruments: Practice Problem & Solution

Rainbow is formed due to: (2000)
Scattering and refraction
Total internal reflection and dispersion
Reflection only
Diffraction and dispersion

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Optical Instruments. Understanding the underlying formula is key to arriving at the correct answer below:

A rainbow is formed due to the dispersion of sunlight by water droplets, followed by total internal reflection and refraction. Therefore, total internal reflection and dispersion is the correct combined effect.
