Final answer:
The frequency is 10 Hz and the wavelength is 3 m.
Step-by-step explanation:
To find the frequency, we need to know the number of waves passing a certain point per second. In this case, 10 waves pass per second. Therefore, the frequency is 10 Hz.
To find the wavelength, we can use the formula speed = frequency x wavelength. The speed is given as 30 m/s and the frequency is 10 Hz. Rearranging the formula, we get wavelength = speed / frequency. Plugging in the values, we find that the wavelength is 3 m.
