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*10^8 m s^-1
Answers
we knew that,
refractive index = speed of light in vaccum/ speed of light in medium
speed of light in glass = speed of light in vaccum / refractive index
= 3× 10^8/1.50
= 3× 10^8/150×10^2
=10^6/50
=10^5/5
=2× 10^5
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
