You dip your finger into a pan of water twice each second, producing waves with crests that are separated by 0.19 m
You dip your finger into a pan of water twice each second, producing waves with crests that are separated by 0.19 m.(a) Determine the frequency of the water waves.
(b) Determine the period of the water waves.
(c) Determine the speed of the water waves. m/s
2 Answers | add yours
a) The frequency of the waves are = 2 Hz (since you are making two pulses every second)
b)The period of the waves is 0.19 m (as the consecutive crests are separated by 0.19 m)
c) V = L x f
v = 0.19 m x 2 S-1 (Hz is actually per second)
v = 0.38 ms-1

I am in 9th grade an I think I can answer this. The answer for both frequency and wavelength:
f = 2 Hz
lambda = 0.19 m
Multiply together to get speed:
v = lambda*f
v = 0.38 meters/second
Reciprocal the frequency to get the period, as per definition, T = 1/f:
T = 0.5 seconds
