What is amplitude in a wave?

Back

Amplitude is the maximum distance that a point on a wave moves from its rest position. It represents the height of the wave.

Front

What are mechanical waves?

Back

Mechanical waves are waves that require a medium (solid, liquid, or gas) to travel through.

Front

What type of wave moves perpendicular to the direction of the wave?

Back

Light waves are an example of transverse waves that move at right angles to the direction of wave propagation.

Front

What is wavelength in a wave?

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

Can sound travel through solids, liquids, and gases?

Back

Yes, sound can travel through all of the above: solids, liquids, and gases.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves do not and can travel through a vacuum.

Front

What is an example of a mechanical wave?

Back

Sound waves are an example of mechanical waves.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).
