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.
A large goose lands in a lake and bobs up and down for a short time. A fisherman notices that the first wave created by the goose reaches the shore in 8.0 s. The distance between two wave crests is 80 cm, and in 2.0s he sees four waves hit the shore. How can the fisherman use these observations to determine how far from the shore the goose landed?
