What is a wave?

Back

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

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.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that the particles of a medium move from their rest position when a wave passes through.

Front

What is wavelength?

Back

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

Front

What is frequency?

Back

Frequency is the number of waves that pass a 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 compression in a wave?

Back

Compression is the part of a longitudinal wave where the particles are pushed together.

Front

What is rarefaction in a wave?

Back

Rarefaction is the part of a longitudinal wave where the particles are spread apart.

Front

How do sound waves travel through different materials?

Back

Sound waves travel faster in solids than in liquids and gases because the molecules are closer together.
