9a - Wave Parts

Front

What two factors affect the amount of energy a wave has?

Back

Frequency and amplitude.

Front

What is a mechanical wave?

Back

A wave that requires a medium (solid, liquid, or gas) to travel through.

Front

Can a mechanical wave travel through a vacuum?

Back

No, a mechanical wave cannot travel through a vacuum because there are no particles to transmit the wave.

Front

What is wavelength?

Back

The distance between two consecutive points in phase on a wave, such as crest to crest or trough to trough.

Front

What is amplitude?

Back

The maximum displacement of points on a wave from its rest position, indicating the wave's energy.

Front

What is a wave trough?

Back

The lowest point of a wave, opposite of the crest.

Front

What type of wave is a sound wave?

Back

Sound waves are longitudinal waves.

Front

What is a crest in a wave?

Back

The highest point of a wave.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle displacement is perpendicular to the direction of wave propagation, while in longitudinal waves, the particle displacement is parallel to the direction of wave propagation.

Front

What is frequency in the context of waves?

Back

The number of waves that pass a given point in one second, measured in Hertz (Hz).
