Waves test questions

Front

What are mechanical waves?

Back

Mechanical waves are waves that require a medium (solid, liquid, or gas) to travel through. Examples include sound waves and water waves.

Front

What is a vacuum?

Back

A vacuum is a space that is completely empty of matter, meaning there are no particles to transmit mechanical waves.

Front

What is frequency in relation to waves?

Back

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

Front

What is amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the wave's energy.

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 wavelength?

Back

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

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves can travel through a vacuum.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the motion of the medium is 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 motion of the medium is parallel to the direction of the wave's travel.
