Answer:
Given parameters
Speed of light in vacuum (c) = 3 × 108 ms-1
Refractive index of glass (ng) = 1.50
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
