light enters from air to glass having refractive index 1.50. What is the speed of light in the glass?
The speed of light in vacuum is 3 x 10^8 ms^-1.
Answers
Answer:
The speed of light in glass is 2 × 10^8 m/s.
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
