Question: The frequency of a tuning fork is 440 Hz. What is the time period of the fork? (2019)

Options:

Correct Answer: 0.00227 s

Exam Year: 2019

Solution:

Time period (T) = 1 / frequency (f) = 1 / 440 Hz ≈ 0.00227 s.

The frequency of a tuning fork is 440 Hz. What is the time period of the fork? (2019)

The frequency of a tuning fork is 440 Hz. What is the time period of the fork? (2019)

Step 1: Understand that frequency (f) is how many times something happens in one second. In this case, the tuning fork vibrates 440 times in one second.
Step 2: The time period (T) is the time it takes for one complete vibration. It is the inverse of frequency.
Step 3: Use the formula for time period: T = 1 / f.
Step 4: Substitute the frequency value into the formula: T = 1 / 440 Hz.
Step 5: Calculate the time period: T = 1 / 440, which is approximately 0.00227 seconds.

Frequency and Time Period – The relationship between frequency and time period is given by the formula T = 1/f, where T is the time period and f is the frequency.
