The speed of a sound wave in seawater is

approximately 1500 m/s.

If this wave is transmitted at 10 ms-1, what

is its wavelength?

Answer in units of cm

I think some of the given is wrong, 10 ms-1, think it is only 10 s-1 which represents the frequency of the wave, and can be use to solve for the wavelength of the sound wave given

wavelength = wave speed / frequency

wavelength = 1500 m/s / 10 s-1

wavelength = 150 m (100 cm / 1 m) = 15000 cm
