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...
