प्रश्न
An obliquely incident light ray bends at the surface due to a change in speed when passing from one medium to another. The ray does not bend when it is incident normally. Will the ray have a different speed in the other medium?

उत्तर
Yes it will. When the medium changes, the speed of light changes.
