ED Waves Vocabulary

Front

What is the relationship between amplitude and sound volume?

Back

Increasing the amplitude of a sound wave increases its volume.

Front

Which type of wave has the longest wavelength?

Back

The wave with the lowest frequency has the longest wavelength.

Front

What is the term for the lowest point of a wave?

Back

The bottom of a wave is called the trough.

Front

How is wave speed measured?

Back

Wave speed is measured in meters per second (m/s).

Front

What does frequency measure in terms of waves?

Back

Frequency measures how many waves occur in a cycle.

Front

What is the definition of wavelength?

Back

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

Front

How does frequency relate to wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is the formula for wave speed?

Back

Wave speed (v) = frequency (f) × wavelength (λ).

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves oscillate perpendicular to the direction of wave travel, while longitudinal waves oscillate parallel to the direction of wave travel.
