Question

A light ray passes from a material of low refractive index to one of high refractive index. Which of the pairs of quantities listed below describes the light ray as it strikes and passes through the interface between the two materials? Match the descriptions below with the statement that best describes the situation.
Statement: A part of the light ray remains inside the low refractive index material.

• A. the angle of refraction is larger than the angle of incidence
• B. the angle of refraction is equal to the angle of incidence
• C. the angle of reflection is larger than the angle of incidence
• D. the angle of incidence equals the angle of reflection
• E. the angle of reflection is smaller than the angle of incidence

Answer 1

The correct option is D the angle of incidence equals the angle of reflection

The part of the light that remains in the medium of low refractive index is actually the reflected ray. We know that in the case of reflection,

$\text{Angle of incidence}=\text{Angle of reflection}$

So, the correct option is D.
