Question

ii] The velocity of light in a medium is 2 x 10"m/s, what
is the veractive index of the medium with respect to
ais, the velocity of wight in air is 8x10® ms.​

Answer 1

Answer:

Correct option is

C

2

Given : Velocity of medium =1.5×10

8

m/sec.

Velocity of light, c=3×10

8

m/sec.

To find : n=?

n=

v

c

n=

1.5×10

8

3×10

8

=2

n=2

Hence, the refractive index of the medium with respect to air is 2.
