Light enters from air to glass having refractive index 1.5. What is the speed of light in the glass? (Speed of light in vacuum is 3*10 8 ms-1
Answers
1.5=3*10^8 ms^-1/ speed of light in glass
the speed of light in glass=3*10^8 ms^-1/1.5
=2*10^8ms^-1
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
