A ray of light incident normally on a glass slab of refractive index 3/2, travels a distance of 6 cm in glass in time t. What will be the distance travelled by the ray in the same time (t) if it travels in air ?

A

3 cm

B

6 cm

C

9 cm

D

`3 sqrt3` cm

Text Solution

Verified by Experts

The correct Answer is:
C
Distance travelled in air .
= n (Distanced travelled in the medium ]
`= 1.5 xx 6 = 9` cm
