Is there an appreciable Doppler effect when the motion of the source is at right angles to a listener? Explain.

Solution 38E STEP 1: The Doppler effect depends on the relative motion of the source and receiver. So when 0 the source moves at an angle of 90 with the observer, we need to calculate the relativistic doppler effect. Suppose the source of light is moving at an arbitrary angle with the direction of the observer, the frequency change will be as follows, V fs= f 0 (1 + C cos )------------------------(1) Where = 1 is the Lorentz factor. 1V2 C2 STEP 2: When the angle between source and observerâ€™s motion will be a right angle, then f = f (1 + V cos ) s...
