The transcript explains how waves change direction when transitioning between mediums due to speed changes. This phenomenon is more noticeable with light but applies to all waves. When a wave enters a slower medium at an angle, one end of the wavefront slows down, altering its direction.

What causes a wave to change direction when it moves from one medium to another?

• A change in its speed

• A change in its frequency

• A change in its amplitude

• A change in its wavelength

When a wave enters a slower medium at an angle, what happens to the wavefront?

• The entire wavefront speeds up

• The entire wavefront slows down

• One end of the wavefront slows down

• One end of the wavefront speeds up

What is the result of one end of the wavefront slowing down?

• The wavefront becomes smaller

• The wave takes a new direction

• The wave stops moving

• The wavefront becomes larger

Which type of wave is most commonly associated with noticeable changes in direction due to speed changes?

• Radio waves

• Light waves

• Water waves

• Sound waves

Do these directional changes occur only with light waves?

• Yes, only with light waves

• No, they occur with all waves

• Only with sound waves

• Only with water waves
