Sound Retest 04.04.2022

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.

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.
