Properties of Waves

What is a wave?

• A wave is a type of greeting commonly used in Hawaii

• A wave is a type of weather phenomenon caused by changes in atmospheric pressure

• A wave is a type of hairstyle popular in the 1980s

• A wave is a disturbance that travels through a medium like air, transferring energy from one point to another.

What is the amplitude of a wave?

• The frequency of the wave

• The maximum disturbance in the medium from its rest position.

• The wavelength of the wave

• The speed of the wave

What is the frequency of a wave?

• The frequency of a wave is measured in meters (m).

• The frequency of a wave is measured in seconds (s).

• The frequency of a wave is measured in kilograms (kg).

• The frequency of a wave is how many waves pass a specific point, it's measured in hertz (Hz).
