Question

What is the period of a sound wave whose wavelength is 20.0 m? Show your work.

Answer 1

Use the basic wave equation....knowing that the speed of sound in air is about ~343m/s:

\[speed= \frac{wavelength}{period} \]

Answer 2

Thank you.

Answer 3

np :)

Answer 4

speed = wavelength/period
343 m/s = 20.0m/period
20/343 = .058
@shane_b is this correct?
