Final answer:
The amplitude does not provide enough information to determine the frequency of a wave; other data or context is required. For a wave with a frequency of 10 Hz, the period is 0.1 s.
Step-by-step explanation:
The amplitude of a wave does not determine its frequency. Therefore, even if the amplitude is known to be 1, it does not give us sufficient information to determine the frequency without additional context or data.
In one of the practice problems provided, the frequency of a wave is given as 10 Hz. To find the period, we can use the formula Period (T) = 1 / Frequency (f). If the frequency f is 10 Hz, then the period T is 1 / 10 which equals to 0.1 seconds. Therefore, the correct answer to the practice problem is:
d. The period of the wave is 0.1 s.
