10. Some cameras determine the distance to the subject by sending out a sound wave and measuring the time needed for the echo to return to the camera. a) Draw a sketch of the scenario and b) Determine how long would it take (to the nearest thousandth of a second) for the sound wave to return to the camera if the subject were 5 m away given the speed of sound was 340 m/s. Your answer
