Question

The angle of incidence is equal to the angle of refraction

• A. True
• B. False

Answer 1

The correct option is B False

Explanation

Snell's Law states that

$\frac{\sin i}{\sin r}=\frac{{\mu }_1}{{\mu }_2}$

where i is the angle of incidence

r is the angle of refraction

${\mu }_1$ and ${\mu }_2$ are the refractive indices of medium 1 and 2.

If refraction is taking place i.e. two different media of different optical densities are involved.

Thus, ${\mu }_1$ is not equal to ${\mu }_2$.

$\sin i$ is not equal to $\sin r$.

$i$ is not equal to $r$.

Thus, the angle of incidence is not equal to the angle of refraction.

Hence, the statement is false.
