Solve the below given problem:
The variation of the density of medium for a sound wave propagating with a speed of \(341\ m/s\) is shown in the below given figure. Calculate the wavelength and frequency of the sound wave.
a) Which method should be used to determine the wavelength of the sound wave from the given graph?
b) The wavelength of the sound wave is \(=\) \(m\)
[Note: Enter your answer in two decimal values]
c) Which formula should be used to calculate the frequency of the sound wave when its speed and wavelength are known?
d) The frequency of the sound wave is \(=\) \(Hz\)
[Note: Enter the answer as a whole number]
