Step 1Let's solve this step by step:
Step 2: Understanding Period and Frequency
f = \frac{1}{T}
- Period (T) is the time it takes to complete one full cycle of a periodic motion or wave - Frequency (f) is the number of cycles completed per unit time - These quantities are mathematically related by the fundamental equation:
Final Answer
Period and frequency are inversely proportional, with period measured in seconds and frequency measured in hertz. Key Insight: f = \frac{1}{T} demonstrates the inverse relationship between frequency and period.
