Waves Test Review

Front

What is wavelength?

Back

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

Front

How do you calculate the wavelength of a wave?

Back

Wavelength (λ) can be calculated using the formula: λ = v/f, where v is the speed of the wave and f is the frequency.

Front

What is frequency?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is the speed of a wave?

Back

The speed of a wave is the distance it travels per unit of time, calculated as speed = wavelength × frequency.

Front

What happens when two waves interfere?

Back

When two waves interfere, they combine to form a new wave pattern, which can be constructive (amplitude increases) or destructive (amplitude decreases).

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet in phase, resulting in a wave with a larger amplitude.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet out of phase, resulting in a wave with a smaller amplitude or cancellation.

Front

What is the Doppler effect?

Back

The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.

Front

What is a seismic wave?

Back

Seismic waves are waves of energy that travel through the Earth, often as a result of geological activity like earthquakes.
