Question

A boat moves up and down on a lake as a wave passes by. If the boat oscillates 10 times in 2 seconds, what is the period of the wave?

0.2 seconds
2 seconds
5 seconds
10 second

Answer 1

a) on edge

Step-by-step explanation:

Answer 2

The period of the wave is the time taken for an oscillation to occur.
The period of the wave can be found by dividing time by the number of oscillations.
The period of the wave is (2s)/(10 oscillations)
2/10= 0.2 seconds

The correct answer is 0.2 seconds.
The wave makes or completes one oscillation in 0.2 seconds.
