A bat at rest sends out ultrasonic sound waves at 54.8 kHz and receives them returned from an object moving directly away from it at 23.8 m/s. What is the received sound frequency?
Please answer in Hz and the answer is not 40,000 Hz.
Homework Answers
Solution,
Frequency, f = [(340 - 23.8)/(340 + 23.8)] x 54.8
Frequency, f = 47.63 kHz

The motion detector used in a physics lab sends and receives 30 kHz ultrasonic pulses. A pulse goes out, reflects off the object being measured, and returns to the detector. The lab temperature is 20 ∘C. Part A) What is the wavelength of the waves emitted by the motion detector? Express your answer in millimeters. Part B) How long does it take for a pulse that reflects off an object 3.0 m away to make a round trip? Express your...

A bat searching for prey emits sound at 90 kHz. The bat flies at 9.0 m/s. The sound emitted by the bat reaches a moth at rest. What frequency is the sound once it reaches the moth? Take the speed of sound in air to be 343 m/s. The moth now flies away at 2 m/s. What is the difference between the frequency that originally reached the still moth and the frequency reaching the moving moth? answer to second part...

Problem 6: Radar gun A police car is at rest parallel to the highway and measures the speed of cars. It sends the signal with a frequency of 1200 Hz, it bounces off the moving car (it is traveling toward or away from the signal emitted) and the radar gun measures the frequency of the signal received. For one car suspected of speeding the received frequency was 1100 Hz. The speed of sound is approximately 350 m/s (note our radar...
