A transparent material like glass allows light to pass
... light inside any transparent material like glass is decided by the refractive index of the material. The more the absolute refractive index, the less is the velocity of light in the medium. But in a material like glass, the refractive index doesn’t depend on the direction of passage of light inside ...
