Explanation:

According to the Question

Refractive index of glass = 1.5

Using Formula

Refractive index of a medium =

Hence  

Speed of light in glass =

Speed of light in glass =

Therefore

Speed of light in the glass is 2 * 10^8 m/s

Dear Student,

◆ Answer -

v = 2×10^8 m/s

● Explaination -

# Given -

c = 3×10^8 m/s

n = 1.5

# Solution -

Speed of light passing through a medium with refractive index n is given by -

v = c / n

Substitute values,

v = 3×10^8 / 1.5

v = 2×10^8 m/s

Therefore, speed of light passing through a glass plate is 2×10^8 m/s.

Thanks dear. Hope this helps you...
