A sonar device emits waves of frequency 40 kHz. The wavelength of the wave in water is 0.032 m. Suppose thatthe device is fixed to the bottom of the ship. It emits a signal and the echo from the ocean bed returns 0.8 secondlater. What is the depth of the ocean at that point?
A student standing in a canyon yells "echo" and her voice produces a sound wave of the frequency of f=0.54 kHz. The echo takes t=4.8s to return to the student. Assume the speed of sound through the atmosphere at this location is v=328 m/s
a) what is the wavelength of the soundwave in meters?
b) input the expression for the distance, d, the canyon wall is from the student. (answer should look like 'd='"
A certain instant camera determines the dis-
tance to the subject by sending out a sound
wave and measuring the time needed for the
wave echo to return to the camera.
How long would it take the sound wave
to return to the camera if the subject were
2.07 m away? The speed of sound is 343 m/s.
Answer in units of s.
