Answer:

f = 687.85 Hz

Step-by-step explanation:

Given that,

The wavelength of sound wave,
\lambda=0.75\ m

We need to find the frequency of the sound wave. The relation between wavelength and frequency is given by :


v=f\lambda

v is speed of sound at T = 35°C = 308.15 K


v=331+0.6T\\\\v=331+0.6* 308.15 \\\\v=515.89\ m/s

So,


f=(v)/(\lambda)\\\\f=(515.89)/(0.75)\\\\f=687.85\ Hz

So, the frequency of the sound is 687.85 Hz.
