Waves and Sound

Front

Which is NOT a transverse wave?

Back

Sound is NOT a transverse wave; it is a longitudinal wave.

Front

What is the unit for frequency?

Back

The unit for frequency is Hertz (Hz).

Front

Calculate the wavelength of a wave with a speed of 400 m/s and a frequency of 50 Hz.

Back

Wavelength = Speed / Frequency = 400 m/s / 50 Hz = 8 m.

Front

A wave created by shaking a rope up and down is called a

Back

A transverse wave.

Front

The distance between successive identical parts of a wave is called its

Back

Wavelength.

Front

What is a transverse wave?

Back

A wave in which the particle displacement is perpendicular to the direction of wave propagation.

Front

What is a longitudinal wave?

Back

A wave in which the particle displacement is parallel to the direction of wave propagation.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum displacement of points on a wave from its rest position.

Front

What is the formula for wave speed?

Back

Wave speed = Frequency x Wavelength.

Front

What is the relationship between frequency and period?

Back

Frequency is the reciprocal of the period; Frequency (f) = 1/Period (T).
