Light enters from air into a glass plate which has a refractive index of 1.50. calculate the speed of light in glass. the speed of light in air is 3 x 108 ms-1.
Answers
So, X= 3x10^8/1.50
Hey Buddy ❤
Your Answer -
Given :
Speed of light in vacuum, c = 3 × 10^8 m/s
Refractive index of glass = 1.50
Formula :
Refractive index of a medium = Speed of light in vacuum/Speed of light in the medium
Solution :
Speed of light in the glass
= Speed of light in vacuum/ Refractive index of glass
=3 × 10^8/1.50
= 2x 10^8 ms-1
Glad To Help :D
