Question

Which of the following phenomena of light are involved in the formation of a rainbow? 

(a) Reflection, refraction, and dispersion 

(b) Refraction, dispersion and total internal reflection 

(c) Refraction, dispersion and internal reflection 

(d) Dispersion, scattering and total internal reflection

Answer 1

The answer is (c) Refraction, dispersion and internal reflection

• Dispersion of light leads to scattering of white light into different color to an angle to cause internal reflection.rs. 
• Refraction bends incident light leading to the formation of rainbow
