Question

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

Answer 1

Answer:

509.7 Hz

Explanation:

The speed of sound in air at room temperature is about 340 m/s

So, the frequency of a sound wave:

$frequency=\frac{speed}{wavelength}$

f = 340/0.667

f ≈ 509.7 Hz
