Find the wavelength of the waves emitted by motion detector

Reference no: EM13300899

The motion detector used in a physics lab sends and receives 49.55 kHz ultrasonic pulses. A pulse goes out, reflects off the object being measured, and returns to the detector. The lab temperature is 17.93C. What is the wavelength of the waves emitted by the motion detector?
