Frequency is defined as the number of cycles of a wave that occur in one second. In the given wave, one complete cycle consists of two peaks and one trough. From the graph, we can see that one complete cycle takes 2 seconds. Therefore, the frequency of the wave is:

frequency = number of cycles/ time

frequency = 1/2 = 0.5 Hz

Hence, the best choice is A) 0.5 Hz.
