Solution :
⏭ Given:
✏ No.of oscillations = 25
✏ Time interval = 8s
⏭ To Find:
- Time period
- Frequency of vibration
⏭ Concept:
✏ Time period is defined as time requires to complete one oscillation.
✏ Frequency is defined as the number of waves that pass a fixed point in unit time or the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
⏭ Formula:
✏ Formula of time period is given by
✏ Formula of frequency is given by
⏭ Calculation:
- Time period
- Frequency
