Final answer:
The period of a wave when the frequency is 2 Hz is the inverse of the frequency, so the period is 0.5 seconds.
Step-by-step explanation:
The period of a wave is the inverse of the frequency. Since a spring toy vibrates at 2 Hz, this means that it completes 2 oscillations each second. To find the period, which is the time it takes to complete one full oscillation, we calculate the inverse of the frequency.
The formula to find the period (T) when given the frequency (f) is:
T = 1 / f
So for a frequency of 2 Hz, the period (T) would be:
T = 1 / 2 Hz = 0.5 seconds
Therefore, the period of the wave produced by the spring toy is 0.5 seconds.
