A boy throws a small stone into a pond. Waves spread out from where the stone hits the water and travel to the side of the pond. The boy notices that eight waves reach the side of the pond in a time of 5.0s. What is the frequency of the waves?
A
0.20 Hz
B
0.63 Hz
C
1.6 Hz
D
40 Hz
Explanation: 

Detailed explanation-1: -Throw a stone into a pond, and you will create ripples. The ripples will undulate outwards from the source of the disturbance towards the edges of the pond. There is a cause and effect relationship. These particular ripples will not happen without the stimulus of your stone-throwing action.

Detailed explanation-2: -Transverse waves are produced when stone is dropped on the surface of water in a pond.

Detailed explanation-3: -When a stone is thrown in a pond, waves are produced in such a manner that the water particles move up and down about their mean positions, and energy moves horizontally away from the impact point. This is a quality of transverse waves.

Detailed explanation-4: -Matter Waves: Any moving object can be described as a wave When a stone is dropped into a pond, the water is disturbed from its equilibrium positions as the wave passes; it returns to its equilibrium position after the wave has passed.
