Homework Statement
Dolphins emit clicks of sound for communication and echolocation. A marine biologist is monitoring a dolphin swimming in seawater where the speed of sound is 1523 m/s. When the dolphin is swimming directly away at 9.8 m/s, the marine biologist measures the number of clicks occurring per second to be at a frequency of 2230 Hz. What is the difference (in Hz) between this frequency and the number of clicks per second actually emitted by the dolphin?
Homework Equations
Fo = Fs(1/(1+v/Vs))
Fo = Frequency heard by observer
Fs = Frequency of source
v = speed of dolphn
Vs = speed of sound in water
The Attempt at a Solution
2230 = Fs(1/1+(9.8/1523))
2230 = (0.9936)Fs
Fs = 2244
Difference between Fs and Fo = 14 Hz. However the answer is showing as incorrect when I input it online. Any idea what I am doing wrong?
