Problem 52E

Unless indicated otherwise, assume the speed of sound in air to be v = 344 m/s. The siren of a fire engine that is driving northward at 30.0 m/s emits a sound of frequency 2000 Hz. A truck in front of this fire engine is moving northward at 20.0 m/s. (a) What is the frequency of the siren’s sound that the fire engine’s driver hears reflected from the back of the truck? (b) What wavelength would this driver measure for these reflected sound waves?

Step-by-Step Solution:

Solution 52E Step 1: In this question, we should measure the frequency of the siren , as measured by the driver reflected from back of his trunk The wavelength of sound wave measured for reflected wavelength Step 2 : Data given Velocity of the engine v = 30sm/s Frequency from source f = 2000sHz Velocity of the truck v = 20 m/s o
