The frequency of a sound wave when the speed of sound is 345 m/s and it has a wavelength of 1.31 m will be 263.358 Hz.
Frequency is defined as the number of repetitions of a wave occurring waves in 1 second.
The given data in the problem is;
f is the frequency of a sound wave=?
v is the speed of sound =345 m/s
[tex]\rm \lambda[/tex] is the wavelength = 1.31 m
The relation between the frequency, speed of sound, and wavelength is given as;
[tex]\rm v = f \lambda \\\\ f = \frac{v}{\lambda} \\\\ f = \frac{345}{1.31} \\\\ f=263.358 Hz[/tex]
Hence the frequency of a sound wave will be 263.358 Hz.
