Waves

Front

What two factors does the speed of sound depend on?

Back

The type of medium and the temperature of the medium.

Front

What type of wave has motion parallel to the direction of the wave?

Back

Longitudinal wave.

Front

What is the relationship between frequency and pitch?

Back

High frequency = High Pitch.

Front

What happens to the pitch of a sound as the source moves away?

Back

The pitch becomes lower.

Front

What is the relationship between low frequency and pitch?

Back

Low frequency = Low Pitch.

Front

Define a transverse wave.

Back

A wave in which the motion of the medium is perpendicular to the direction of the wave.

Front

What is wavelength?

Back

The distance between two consecutive crests or troughs in a wave.

Front

What is the formula for wave speed?

Back

Wave speed = Frequency × Wavelength.

Front

What is the effect of temperature on the speed of sound?

Back

As temperature increases, the speed of sound increases.

Front

What is a crest in a wave?

Back

The highest point of a wave.
