Question

A light ray is traveling from medium A to B. If the value of $\frac{\sin i}{\sin r}$ is1 implies that the light ray bends towards the normal.

• A. greater than
• B. lesser than
• C. equal to

Answer 1

The correct option is A greater than

Since the light ray bends towards the normal, angle of refraction is less than the angle of incidence.
$r<i$
$⟹\sin r<\sin i$
$\frac{\sin i}{\sin r}>1$
