Question
Sound waves used to determine the depth of water in a lake are emitted from a boat with a period of 2.5 x 10^-5 s
Sound waves used to determine the depth of water in a lake are emitted from a boat with a period of 2.5 x 10^-5 s . The wavelength of the waves in the water is 3.8 x 10^-2 m and the reflected pulse is received 9.6 x 10^-2 s after the pulse is emitted. Determine the speed of the pulse in the water. How deep is the lake at that location?
