Two trains A and B moving with speeds 20m//s and 30m//s respectively in the same direction on the same straight track, with B ahead of A . The engines are at the front ends. The engine of train A blows a long whistle. Assume that the sound of the whistle is composed of components varying in frequency from f_(1) = 800 Hz to f_(2) = 1120 Hz , as shown in the figure. the spread in the frequency (highest frequency - lowest frequency) is thus 320 Hz . the speed of sound in still air is 340 m//s . (5) The distribution of the sound intensity of the whistle as observed by the passengers in train A is best represented by
