Question

A temple bell produces 400 vibrations in 1 second. Find the time period of its vibration.​

Answer 1

Answer:

1/400

Explanation:

frequency =1/ lambda

Answer 2

The time period of its vibration is 0.0025 seconds.

Explanation:

The bell of the temple rings due the vibrations that occurs on the metal due to striking it with the other metal to make sound.

Since, we know that the vibrations in the metal responsible for the sound and we also know the number of vibrations that are taking place within a second. we can calculate the time period of each vibration taking place.

From the given,

   A bell in the temple produces 400 vibrations in 1 second.

Formula for finding frequency = Vibration\Second.

                                           $= \frac{400}{1}$

                                     = 400 Hz.

Formula for finding Time period = 1\frequency

                                            $= \frac{1}{400}$

                                     = 0.0025 second.

If 400 vibrations are taking place in one second, then time taken for or one vibration would be $\frac{1}{400}$ second.

So, the time would be 0.0025 second, That means one vibration will take place in 0.0025 in seconds.
