Question

Light ray travels from air to glass. Why?​

Answer 1

Answer:

Hope this answer helps you!

Explanation:

When a light ray traveling through air enters glass it slows down. Refraction is the bending of light as it crosses a boundary between two different transparent materials. This bending effect takes place whenever light slows as it moves from one material into another.

Answer 2

Answer:

When a ray of light passes from a less dense material (eg air) into a denser material (eg glass or water) it is bent away from the surface between the two materials. This means that in this situation the angle of refraction is always less than the angle of incidence.
