Behavior of Waves

What is the definition of frequency?

• “how high” the wave is. It is the maximum distance the air particles travel from undisturbed position.

• The distance between one wave and the same point on the next wave usually measured in metres (m).

• The number of waves produced by a source each second. It is measured in Hertz (Hz).

What does a wave carry from place to place?

• energy

• matter

• people

What is refraction in the context of wave behavior?

• The reflection of waves off a surface

• The absorption of waves by a medium

• The bending of waves due to a change in speed as they pass from one medium to another

• The transmission of waves without any change

What happens to a wave when the change in speed is greater as it passes through different media?

• The wave bends less

• The wave does not change direction

• The wave bends more

• The wave stops moving
