    1. Since wave speed in a medium is constant, frequency is inversely proportional to wavelength. Therefore, source A with maximum frequency corresponds to the green curve having the shortest wavelength and most cycles. Source C with minimum frequency corresponds to the blue curve having the longest wavelength. Source B corresponds to the intermediate red curve.
