Waves Review Physics

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is wavelength?

Back

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

Front

What is frequency?

Back

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

Front

What is the relationship between speed, frequency, and wavelength?

Back

The speed of a wave (v) is equal to its frequency (f) multiplied by its wavelength (λ): v = f × λ.

Front

What is amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the energy of the wave.

Front

What is the difference between transverse and longitudinal waves?

Back

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

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

How do you calculate the frequency of a wave given its wavelength and speed?

Back

Frequency (f) can be calculated using the formula: f = v / λ, where v is the speed and λ is the wavelength.

Front

What is the unit of measurement for wavelength?

Back

Wavelength is typically measured in meters (m).
