Question

What happens to ray of light when it moves from rarer to denser medium?

Answer 1

Answer:

Explanation:

When a ray of light is moving from rarer to denser medium it moves towards the normal.

Answer 2

Answer:

You saw that light bends toward the normal in this situation, and that the angle in the denser medium will be smaller than the angle in the rarer medium. ... When light travels from a denser medium to a rarer medium, it bends away from the normal, as illustrated to the left. This behavior follows from Snell's Law.
