Homework Help: Physics

Posted by confused on Thursday, January 24, 2013 at 1:24am.

A water wave is generated in a ripple tank by an oscillator that vibrates 50 times in 30 seconds. A given trough of the wave travels 50.0 cm in 15 seconds. What is the wavelength of the water wave? Produce all your workings.

I got
50/30 = 1.67 vibrations per second = frequency

.5/15 = .033 waves per second = velocity

F(W) = V so W = V/F

But then my answers don't seem to be correct. Can someone please help out?
Thank you
