Question

One property of a wave is that it changes speed from one substance to another. What happens to the light wave when it travels from the air and through the glass?

Answer 1

Step-by-step explanation:

When light travels from air to glass, it slows down due to the change in the refractive index. This causes the wave to bend, a phenomenon known as refraction. The amount of bending depends on the difference in refractive indices between the two materials, and the angle of the incoming wave.
