A source of sound of frequency 2000 Hz moves towards a wall velocity u = 6 cm//s and the wall moves towards the source at v = 3 cm//s. What is the beat frequency registered by a receiver moving towards the wall at w = 2 cm//s, it being in between the source and the wall ? Velocity of sound = 340 m//s
