What is a wave?

Back

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

What is wavelength?

Back

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

What is frequency?

Back

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

What is amplitude?

Back

Amplitude is the maximum distance a wave moves from its rest position, indicating the energy of the wave.

What is a crest?

Back

A crest is the highest point of a wave above the line of origin.

Back

A trough is the lowest point of a wave below the line of origin.

How does wavelength relate to frequency?

Back

Shorter wavelengths correspond to higher frequencies, while longer wavelengths correspond to lower frequencies.

What is the relationship between amplitude and sound?

Back

Higher amplitude means louder sound, while lower amplitude means quieter sound.

Front

What is a wave's line of origin?

Back

The line of origin is the baseline level where the wave would rest if there were no disturbance.

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium (like air or water) to travel through, while electromagnetic waves can travel through a vacuum.
