You dip your finger into a pan of water twice each second, producing waves with crests that are separated by 0.15 m. (a) Determine the frequency of the water waves.  Hz (b) Determine the period of the water waves.

1. Shown below is the plot of a wave function that models a wave traveling along the positive x- direction at t=0.00s and t=2.00s. The dotted line is the wavefunction at time t=0.00s. Estimate the amplitude, wavelength, velocity and period of the wave. t = 0.00 s t = 2.00 s y(m) 4 0.40 0.30 0.20- 0.10 0.00 -0.10 -0.20 -0.30 -0.40 0 0.2 0.4 0.6 0.8 Amplitude: A = 0.3 Wavelength: A = 1 Velocity: v=0.5 Period: T=0 XX 1 S 1.2 1.4 1.6 1.8 2 m m/s x(m) m

A pond is 12 metres across. The crests of two successive waves are 60.0 cm apart and they each move across the pond in 15 seconds. a) What is the velocity of the waves? b) What is the frequency of the waves? c) What is the period of the waves?
