## Question:

If a dog whistle has a frequency of 30000 hertz, what is the wavelength of the sound emitted (Approximate speed of sound is 340 m per s)?

## Wavelength

Consider two identical in points in two consecutive waves. The distance between these two points is called wavelength. Wavelength is measured in metres. In other words, wavelength can also be defined as the distance after which the shape of wave repeats.
