T=30/50 = 0.6 s.
v=s/t= 0.5/15 = 0.033 m/s
λ=vT=0.033•0.6= 0.02 m
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

Frequency f = number of oscillations/times taken = 50/30s = 1.66Hz
Velocity of wave v = distance/time = 0.5m/15s = 0.033m/s
v = fλ
λ = v/f = 0.033/1.66 = 0.02
Velocity of wave v = distance/time = 0.5m/15s = 0.033m/s
v = fλ
λ = v/f = 0.033/1.66 = 0.02
