Answer:
frequency: 600 Hz
Wavelength: 0.572 m
Step-by-step explanation:
The frequency of the sound is equivalent to the number of beats per second, so the frequency is 600 Hz.
Then, we can calculate the wavelength as follows

Where v is the speed and f is the frequency. Replacing v = 343 m/s and f = 600 Hz, we get:

Therefore, the wavelength is 0.572 m.
