Question

If the frequency of a sound wave is 990 Hz, calculate its wavelength. (Assume the air temperature is 0°C.) = ________ m

Answer 1

Explanation:

Speed of sound at 0°C

V = 331 + 0.6T

V = 331 + 0.6(0)

V = 331m/s

F = 990Hz

Using

V = wavelength × Frequency

Wavelength = V/F

Wavelength = 331/990

Wavelength = 0.334m
