Brief Explanations
- For statement #1: Frequency is the number of vibrations per unit time. A large number of vibrations in a short time means high frequency. Period $T = \frac{1}{f}$, so high frequency means a small period, making this statement false.
- For statement #2: By definition, period ($T$) and frequency ($f$) are reciprocals: $T=\frac{1}{f}$, so this is true.
- For statement #3: Since $T=\frac{1}{f}$, period and frequency have an inverse (inversely proportional) relationship, so this is true.
