The time required to pass the light through a glass slab of 2 mm thick is `(mu_("glass")=1.5)`

Refraction of light passing through a glass slab.

The time required for the light to pass through a glass slab ( refractive index=1.5) of thickness 4 mm is (c= 3xx10^(8)ms^(-1) speed of light in free space)

The time required for the light to pass through a glass slab (refractive index= 1.5 ) of thickness 4 mm is (c= 3xx10^(8) m s^(-1) , speed of light in free space)
