Waves and Sound

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter, typically characterized by oscillations.

Front

What is frequency in relation to waves?

Back

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

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.

Front

What is the trough of a wave?

Back

The trough is the lowest point of a wave.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave move from their rest position, indicating the wave's energy.

Front

What is wavelength?

Back

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

Front

How does sound travel through different mediums?

Back

Sound travels faster in solids than in liquids, and faster in liquids than in gases due to the density and arrangement of molecules.

Front

What is the relationship between pitch and frequency?

Back

Pitch is the perceived frequency of a sound; higher frequencies correspond to higher pitches.

Front

What is sound energy?

Back

Sound energy is a form of energy produced by vibrating sound waves.

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.
