Question

Define the term vibration. What do you mean by frequency of vibration? What will happen to the frequency of vibration if its time period is increased?

Answer 1

1: Vibration

The to and fro movement of a particle about its mean position is called vibration.

2: Frequency

The number of vibrations in one second is called the frequency of vibration.

3: Effect of time period on frequency:

1. Time period is the time taken by a body or particle to complete one vibration or oscillation.
2. $Frequency=\frac{1}{Time}$.
3. Frequency is inversely proportional to time.
4. If time increases the frequency decreases.
