Light enters from air into a glass plate which has a refractive index of 1.50. Calculate the speed of light in glass. The speed of light in air is ms-1.
Answers
= (speed of light in air/vaccum)/(speed of light in that medium)
= c/v
∵c = 3×10^8 m/s
⇒1.50 = (3×10^8)/v
⇒v = (3×10^8)/1.50
⇒v = 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
