Define the velocity, wavelength, and frequency of a wave and give an example of each. Use symbol notation in the definitions


The velocity (v) of a wave is the distance the wave travels per unit of time. The
velocity of a sound wave in air is 330 m/s at 0°C. The wavelength (?) is the distance
between two similar points on any two consecutive waves. The wavelength of the
sound wave is given in meters. The frequency is the number of cycles per unit time.
The frequency (f) of the sound wave is measured in Hz.
