Question

36.When a ray of light travels from rarer medium to denser medium then light ray bends ……… the normal. *
1 point
(A) parallel to
(B) perpendicular
(C) away from
(D) towards​

Answer 1

D) When a ray of light travels from rarer medium to denser medium then light ray bends towards the normal.

Answer 2

When a ray of light travels from rarer mediu. to denser medium then the light ray bends towards the normal .

Therefore , Option D) towards is Correct .

___________________

Optically Rarer :

Medium in which the speed of light is more is known as Optically Rarer Medium .

Eg : Water is an optically rarer medium to glass .

Optically Denser :

Medium in which the speed of light is less is known as Optically Denser Medium .

Eg : Water is an optically denser medium as compared to air .

• When a ray of light enters from optically rarer medium into optically denser then the light ray bends towards the normal .
• When a ray of light enters from optically denser medium into optically rarer then the light ray goes away from the normal .
