Answer:

The phenomena of bending of light ray when it travels from

one medium to another medium due to change in speed of light

is called “refraction of light”.

According to optics, the medium

in which speed of light is

more is called rarer medium.

Only when the light ray travels along the normal to the surface,

it does not change the direction.

In all other cases, light bends during refraction.

Rarer medium

According to optics, the medium

in which speed of light is

less is called denser medium.

Denser medium

To understand refraction of light through figures, the following terms are important.

At the point of incidence where the light ray

strikes the interface between the two media,

a line drawn perpendicular to the surface

is known as normal. It is labeled as N

with the help of dotted line in the figure.

NORMAL

The angle between the incident light ray and

the normal is called angle of incidence. Denoted by Li

ANGLE OF

INCIDENCE ( i)

The angle between the refracted light ray and

the normal is called angle of refraction. Denoted by Lr

ANGLE OF

REFRACTION ( r)

When light ray travel from rarer medium

to denser medium,

the refracted light ray

deflects closer to the normal.
