Consider two submarines A and B traveling through water. Submarine A is moving at 5.00 m/s. Submarine B is moving at 8.00 m/s while emitting a sonar wave at a frequency of 1.20 * 103 Hz. The speed of sound in water is 1.50 * 103 m/s and there is no wind. Enter the answers in scientific notation. What frequency is detected by an observer riding on submarine A as the submarines approach each other? What is the observed wavelength of the sonar wave as the submarines approach each other?
