Energy: Waves

Front

What are transverse waves?

Back

Transverse waves are waves that carry energy at a right angle or perpendicular to the direction of energy flow. Examples include light waves and waves on a string.

Front

What is the crest of a wave?

Back

The crest is the highest point on a wave.

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum height of a wave from its rest position, indicating the energy of the wave.

Front

How does amplitude affect sound?

Back

If a sound wave has a big amplitude, it will produce a loud sound.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through a medium without transferring matter.

Front

What are longitudinal waves?

Back

Longitudinal waves are waves in which the particle displacement is parallel to the direction of wave propagation. An example is a sound wave.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is frequency?

Back

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

Front

What is wave speed?

Back

Wave speed is the speed at which a wave travels through a medium, calculated as the product of frequency and wavelength.

Front

What is the trough of a wave?

Back

The trough is the lowest point on a wave.
