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...

Ah yes, don't know how I missed that. Cheers mate.

The units are metres. Cant see why 784m is being marked as incorrect.

Homework Statement What is the wavelength λ of a wave that has a speed of 160 m/s and a period of 4.9 ms? Homework Equations λ = vT The Attempt at a Solution λ = 160 x 4.9 = 784m However this answer is showing up as inccorect when I submit it online. What am I doing wrong?
