Question

A. 0.2 s
B. 200 m/s
C. 4 s
D. 0.2 m

Answer

The correct answer is 0.2 s. T = 0.2.

Explanation

The period is 0.2 s because period is one divided by frequency. This keeps period anchored to Properties of waves instead of mixing up frequency, period, wavelength or wave speed.

Common mistake
