Light enters from air to glass having refractive index 1.50. What is speed of light in glass
Answers
R.I.=c(speed of light in air)/v(speed of light in any medium)
=)1.50=3*10^8/v
=)v=3*10^8/1.50
therefore,v=2*10^8
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
