Question

The bending of light on passing from one medium to another is called refraction.

• A. True
• B. False

Answer 1

The correct option is A True

Explanation

1. Refraction of light is a phenomenon in which the ray of light bends as it travels from one medium to another.
2. The cause of this is the change in the optical density of the media.
3. This changes the speed of light and hence the ray appears bent.
4. The relation between the angle of refraction and incidence is given by Snell's Law

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

where i and r are the angle of incidence and refraction respectively.
${\mu }_1$ and ${\mu }_2$ are the refractive indices of medium 1 and 2 respectively.

Hence, the statement is true.
