Answer:

Answer:

Given parameters

Speed of light in vacuum (c) = 3 × 108 ms-1

Refractive index of glass (ng) = 1.50

Find out

The speed of light in the glass

Formula

Refractive index of a medium  = Speed of light in vacuum/Speed of light in the medium

Refractive index of glass = Speed of light in vacuum/Speed of light in the glass

Speed of light in the glass (v) = Speed of light in vacuum/ Refractive index of glass

v = c/ng

v = (3 × 108)/1.50

v = 2 × 108 ms-1

Answer

The speed of light in glass = v = 2 × 108 ms-1
