Q
Q: A tuning fork produces a sound wave of frequency 440 Hz. What is the period of this wave?
Solution:
The period T is the reciprocal of frequency f. T = 1/f = 1/440 Hz = 0.00227 s.
Steps: 5
Show Steps
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.
