Question

define the refractive index of transparent medium the speed of the light in a medium of absolute refractive index is 1.5 is 2 into 10 raise to 8 metre per second what is the need of the light in vacuum​.

Answer 1

Answer:

Speed of light in vacuum is 3.8×10*8m/sec(3×10*8m/sec)

Explanation:

Refractive index =speed of light in vacuum /speed of light in that medium

1.5=C/2×10*8

C=2×1.5×10*8

C=3×10*8m/sec=3.8×10*8m/sec

Answer 2

ratio of speed of light in a vacuum to speed of light in any other medium
