Question
The diagram represents a wave traveling to the right along an elastic medium. If the frequency of the wave is 0.25 cycle per second, what is the period of the wave?A 1.5 sB 1.9 sC 2.5 sD 4.0 s
Solution
The period of a wave is the reciprocal of the frequency. In this case, the frequency of the wave is given as 0.25 cycles per second.
To find the period, you simply take the reciprocal of the frequency.
So, the period T = 1/frequency = 1/0.25 = 4 seconds.
Therefore, the correct answer is D, 4.0 seconds.
