Question

A mosquito vibrates 300 times in 4 minutes. Calculate its frequency and time period.

Answer 1

Given : A mosquito vibrates 300 times in 4 minutes.

　

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 = 300/240

→ Frequency = 1.25 hertz

　

→ Time period = 1/1.25

→ Time period = 0.8 seconds

　

Therefore,

1. Frequency = 1.25 hertz.
2. Time period = 0.8 seconds.
