A source of sonic oscillations with frequency n=1700 Hz and a receiver – InterviewSolution

1.	A source of sonic oscillations with frequency n=1700 Hz and a receiver are located on the same normal to a wall. Both the source and the receiver are stationary, and the wall recedes from the source with velocity u=6.0 cm/s. Then the beat frequency registered by the receiver is approximately (velocity of sound is v=340 m/s)
Answer» A source of sonic oscillations with frequency $n = 1700 H z$ and a receiver are located on the same normal to a wall. Both the source and the receiver are stationary, and the wall recedes from the source with velocity $u = 6.0 c m / s$ . Then the beat frequency registered by the receiver is approximately (velocity of sound is $v = 340 m / s$ )
