Waves

What is a transverse wave?

A wave where vibrations are perpendicular to the direction of travel.

What is a longitudinal wave?

A wave where vibrations are parallel to the direction of travel.

Give an example of a transverse wave.

Light waves or water waves.

Give an example of a longitudinal wave.

Sound waves.

What is the crest of a wave?

The highest point of a transverse wave.

What is the trough of a wave?

The lowest point of a transverse wave.

What is compression?

Particles pushed close together in a longitudinal wave.

What is rarefaction?

Particles spread apart in a longitudinal wave.

What affects loudness in a wave?

Amplitude.

What affects pitch in a wave?

Frequency.

What is wavelength?

The distance between two matching points on a wave.

What is frequency?

The number of waves passing a point each second.

What is the formula for wave speed?

v = f x wavelength

What is the formula for wave frequency?

f = v / wavelength

What is the formula for wavelength?

wavelength = v / f
