Waves: Refraction

The video explains how waves behave when passing at an angle from one medium to another, focusing on the concept of refraction. It describes how waves bend due to changes in speed when moving between different media, such as air and water or through a diamond. The slowing down or speeding up of light causes this bending, known as refraction.

What happens to waves when they pass at an angle from one medium to another?

• They change color.

• They disappear.

• They change speed and direction.

• They increase in size.

When light waves move from air to water, what happens to their speed?

• They slow down.

• They speed up.

• They remain constant.

• They stop completely.

What is the term used to describe the bending of waves due to a change in speed?

• Diffraction

• Refraction

• Absorption

• Reflection

In the context of refraction, what happens to light when it enters a diamond?

• It changes color.

• It gets absorbed.

• It speeds up or slows down.

• It reflects back.

What causes the phenomenon of refraction?

• A change in light's color.

• A change in light's speed.

• A change in light's temperature.

• A change in light's direction.
