Question

O

The speed of light inside a medium is (2.0x108m/s). What is the index of refraction (n) of the medium?

Answer 1

see

below

Step-by-step explanation:

refractive index = speed of light in vacuum / speed of light in medium

light travels at a speed of 3.0 x 10^8 m/s in vacuum

refractive index = 3.0 x 10^8 / 2.0 x 10^8

refractive index = 1.5
