Question: A tuning fork produces a sound wave of frequency 440 Hz. What is the time period of the sound wave?

Options:

Correct Answer: 0.00227 s

Solution:

The time period T is the reciprocal of frequency f. Thus, T = 1/f = 1/440 ≈ 0.00227 s.

A tuning fork produces a sound wave of frequency 440 Hz. What is the time period of the sound wave?

A tuning fork produces a sound wave of frequency 440 Hz. What is the time period of the sound wave?

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 time period (T) is the time it takes for one complete wave cycle to pass a point. It is the opposite of frequency.
Step 3: Use the formula for time period: T = 1/f.
Step 4: Substitute the frequency into the formula: T = 1/440.
Step 5: Calculate the value: T = 1/440 ≈ 0.00227 seconds.
Step 6: Conclude that the time period of the sound wave is approximately 0.00227 seconds.

Frequency and Time Period – The relationship between frequency and time period, where the time period is the inverse of frequency.
