problem 1: A person on a dock counts 8 troughs going by in 20 seconds. The distance between the troughs is .75m. Determine the speed of the waves?

problem 2: A person shouts at a cliff and hears the echo 4.0 seconds later. The period of the sound is .012 s and the wavelength is 4.0 m. How far away is the cliff?

problem 3: Water waves in a shallow dish are 6.0cm long. At one point, the water oscillates up and down at a rate of 4.8 oscillations per second. Find out the speed of the wave?

problem 4: Water waves on a lake travel 4.4m in 1.8 seconds and their period is 1.2 seconds, find out the wavelength?
