Question

The refractive indices of four substances W, X, Y, Z are $1.20,1.77,1.36,1.50$ respectively. When light passes from air into these materials, it refracts maximum in

• A. W
• B. X
• C. Y
• D. Z

Answer 1

The correct option is B X

Refraction is the deviation of incident light from its path of incidence.

Hence, more the bending more the refraction. And the deviation increases with increase in refractive index.

Hence, $X$ having maximum refractive index refracts maximum.

Answer-(B).
