Question

The frequency of ringing bell in a temple 400 vibration/sec,then calculate the periodic time of it

Answer 1

Answer:

given that frequency=400hz.frequncy = 1/time=1/400= 0.0025 sec

Answer 2

Given : The frequency of ringing bell in a temple 400 vibration/sec.

　

To find : What is its time period and frequency?

　

Using formula :

1) Frequency = Number of times the pendulum oscillates/Total number of time taken.

　

2) Time period = Number of oscillation per second/Frequency.

　

Calculations :

→ Frequency = 400/1

→ Frequency = 400 hertz

　

→ Time period = 1/400

→ Time period = 0.0025 seconds

　

Therefore,

1. Frequency = 400 hertz.
2. Time period = 0.0025 seconds.
