light enters from air to glass having refractive index 1.50 what is the speed of speed of light in glass the speed of light in vacuum in 3*10 m/s
Answers
----------------------------- =1.5
speed of light in glass
= 3 x 10^8m
-------------------- = 1.5
s.l.glass
s.l.glass= 3 x 10^8
------------- =10^8
1.5 -------
0.5
2x10^8 m/s..
hope this helped you ...
thanks
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
