Question

What frequency (in Hz) of sound at 20.1 degrees Celsius has a wavelength of 1.71 m?

Answer 1

The frequency of sound at the given temperature is 200.58 Hz.

Frequency of sound at the given temperature

The frequency of sound at the given temperature is calculated as follows;

v = fλ

f = v/λ

where;

• v is speed of sound at 20 ⁰C = 343 m/s
• λ is wavelength of the sound = 1.71 m

f = 343/1.71

f = 200.58 Hz

Thus, the frequency of sound at the given temperature is 200.58 Hz.
