Sound and Waves Review

Frequency is defined as...

• Number of waves or cycles generated per second.

• The maximum displacement of a wave from its equilibrium position.

• The time interval between two consecutive waves.

• The distance between two identical positions on two consecutive waves.

A wave machine generated waves with a wavelength of 0.080 m at a constant wave speed of 17 m/s. Calculate the frequency of the waves.

• 212 Hz

• 1.36 Hz

• 0.00470 Hz

• 16.92 Hz

• 1.36

The speed of sound in air is 340 m/s. The frequency of the sound waves generated by my voice is 720 Hz. Calculate the wavelength of sound of my voice.
