The period of a wave is simply the reciprocal of its frequency, and frequency can be calculated with the formula:
frequency = speed / wavelength.
Given:
speed = 2 m/s
wavelength = 0.4 m
frequency = 2 m/s / 0.4 m = 5 Hz
Period = 1 / frequency
Period = 1 / 5 Hz = 0.2 seconds
Therefore, the correct answer is:
0.2 seconds.
