Question

Sound waves with a constant frequency of 250 hertz are traveling through air at STP. Calculate the wavelength of the sound waves.

Answer 1

What is the relationship between a wave's:
- frequency, \( f \)
- wavelength, \( \lambda \)
- speed, \( v \)

It is
\[ v = \lambda f \]

For this sound wave, you know two of the variables and hence you can deduce the third.
