Answer:
4.753 m/s
Step-by-step explanation:
We know that the sound wave has a frequency of 3.395 Hz and a wavelength of 1.4m and we need to find the speed of the wave.
The speed of the wave can be calculated as:

Where λ is the wavelength and f is the frequency of the wave.
So, replacing λ by 1.4 m and f by 3.395 Hz, we get:

Therefore, the speed of the wave in than medium is 4.753 m/s
