{1}the graph of 2 sound waves having the same amplitude but different frequency
roughly wave A and B have same amplitude. but B has more frequency than A as in same time period, more oscillations are produced in B.
in C the frequency is little smaller than B but amplitude is maximum.
frequency idea we get by the number of times the curve crosses the time axis, and amplitude idea we get from the height of the crest.
