Question
If the velocity of sound in air is 340 m/s, find
a) wavelength when frequency is 256 Hz
b) frequency when wavelength is 0.85 m
Solution
a) The formula to find the wavelength (λ) is given by the speed of sound (v) divided by the frequency (f). So, λ = v/f.
Substituting the given values, we get λ = 340m/s / 256Hz = 1.328125m.
b) The formula to find the frequency (f) is given by the speed of sound (v) divided by the wavelength (λ). So, f = v/λ.
Substituting the given values, we get f = 340m/s / 0.85m = 400Hz.
