A tuning fork produces a sound wave of frequency 440 Hz. What is the period of this wave?
Correct Answer: 0.00227 s
- Step 1: Understand that frequency (f) is how many times a wave repeats in one second. In this case, the frequency is given as 440 Hz.
- Step 2: Know that the period (T) is the time it takes for one complete wave to pass a point. It is the opposite of frequency.
- Step 3: Use the formula for period, which is T = 1/f.
- Step 4: Substitute the frequency into the formula: T = 1/440 Hz.
- Step 5: Calculate the period: T = 1/440 = 0.00227 seconds.
- Frequency and Period Relationship – The period of a wave is the inverse of its frequency, calculated using the formula T = 1/f.
