please explain part d An ambulance moving in still air at a constant speed of v, =135.0 km / h, on a straight5.road, has a horn that emits sound at a frequency f =1450 Hz. Assume that the speed of soundin the still air is v=350 m/s.a) What is the frequency fi of the sound heard by an observer standing still on the road as theambulance approaches?b.) What is the wavelength, 4, of the sound in the still air directly in front of the ambulance asit is approaching?c.) What is the frequency f, of the sound heard by a moving observer moving directly towardthe approaching ambulance at a speed v, = 95.0km / h?d.) Suppose that the sound from the ambulance is reflected off of a reflector moving directlytoward the approaching ambulance at a speed v, -95.0km / h. Assuming that the sound canbe heard, what is the frequency f, of the reflected sound wave heard by the ambulancedriver?
