Unit 3.2 Waves

Front

What is a wave?

Back

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

Front

What is amplitude in a wave?

Back

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

Front

What is frequency?

Back

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

Front

What is wavelength?

Back

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

Front

What are the two main types of waves?

Back

The two main types of waves are transverse waves and longitudinal waves.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particles of the medium move perpendicular to the direction of the wave's travel.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the particles of the medium move parallel to the direction of the wave's travel.

Front

What is a medium in the context of waves?

Back

A medium is the substance through which a wave travels, such as air, water, or solid materials.

Front

Why can't sound travel in outer space?

Back

Sound cannot travel in outer space because there is no medium (like air) for the sound waves to travel through.

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.
