Observations: Pulses and wave motion and Mathematical descriptions of a wave
Assume that the speed of sound in air is 340 m/s for all of these problems unless stated otherwise.
Dolphin sonar A dolphin has a sonar system that emits sounds with a frequency of 2.0 x 105 Hz. Determine everything you can about this sound wave. Remember that the sounds emitted by the dolphin travel in water.
