Question

Find the frequency of a sound wave moving in air at room temperature with a wavelength of
0.667 m.

Answer 1

Find the frequency of a sound wave moving in air at room temperature with a wavelength of 0.667 m.

The speed of sound in air at room temperature:

$$c_s = 340\,m/s$$

So, the frequency of a sound wave:

$$f = \frac{c_s}{\lambda}$$ $$f = \frac{340\,m/s}{0.667\,m} = 509.7\,Hz$$

Answer: $f = 509.7\,Hz$
