Question

Light travels 1.5 times faster in air than a given medium. What is the refractive index of that medium with respect to air ? Pls don't spam

Answer 1

Answer:

hope it helps

pls mark as brainliest

Explanation:

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.
