Question

The speed of light in a transparent medium is 0.6 times that of its speed in vacuum What is the refractive index of medium?​

Answer 1

Answer:

Refractive index mu=speed of light in air/speed of light in medium.

so mu=c/v

given, v=0.6c

so, mu=c/0.6c

therefore, mu=1.67

Explanation:

i hope you know the symbol of mu.I dont have it in my keyboard.

hope it helps u. thanku!

Answer 2

Answer:

The speed of light in a transparent meduim is 0.6 times that of its speed in vacuum

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

RI = 1/0.6 = 5/3
