The drawing shows three situations - A, B, and C - in which an observer and a source of electromagnetic waves are moving along the same line. In each case the source emits a wave that has a frequency of 4.57 x 1014 Hz. The arrows in each situation denote velocity vectors of the observer and source relative to the ground and have the magnitudes indicated (vor 2v), where the speed v is 2.6 x 106 m/s. Calculate the observed frequency in each of the three cases. A: f= B: f= i i C: f= i A B с ··· Observer Source 1,1 ? 2v
