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.
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?
