Solution

The correct option is B False
Given: $\frac{s i n i}{s i n r} > 1$
$\Rightarrow$ $s i n i > s i n r$
$\Rightarrow$ Angle of refraction will be smaller than the angle of incidence.
$∴$ Light ray will be bent towards normal.

Q. When light is travelling from one medium to another and

\frac{s i n i}{s i n r}

> 1, then the light will bend away from normal.

When light passes from A to B, the value of $\frac{s i n i}{s i n r}$ is greater than 1. It implies that the light ray bends towards the normal.

Q. When light is travelling from one medium to another and

\frac{sin i}{sin r}

> 1, then the light will bend towards the normal.

A light ray is passing from medium $A$ to $B$ and $\frac{s i n i}{s i n r}$ is greater than one. This implies:
