Waves: Wavelength, Frequency, and Amplitude

Front

What is a wave?

Back

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

Front

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

Front

Define amplitude.

Back

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

Front

How does energy relate to wavelength?

Back

As energy in a wave increases, the wavelength decreases.

Front

How does energy relate to amplitude?

Back

As energy in a wave increases, the amplitude increases.

Front

What is the formula for wave speed?

Back

Wave speed (v) = Wavelength (λ) × Frequency (f).

Front

What happens to frequency if wavelength increases while speed remains constant?

Back

If wavelength increases and speed remains constant, frequency decreases.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as one increases, the other decreases.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particles of the medium move perpendicular to the direction of the wave's travel.
