Question

2. What happens when light travels from rarer
to denser medium?​

Answer 1

Explanation:

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. As you saw before, the larger angle must be in the medium having the lower index of refraction
