Figure shown is a graph, at a certain time t, of the displacement function S (x, t) of three sound waves 1,2 and 3 as marked on the curves that travel along an x-axis through air. If p 1 , p 2 and p 3 represent their pressure amplitudes respectively, then correct relation between them is:
Text Solution
Verified by ExpertsThe correct answer is:
B
Thus, pressure amplitude is highest for minimum wavelength, other parameters 
and 
being same for all. From given graphs.
