Question

4. Define a) oscillaton b) time period

Answer 1

Answer:

Oscillation - To and fro motion of an object or particles in a medium is called oscillation. Time period - The time required for one oscillation is called time period. Frequency - The oscillations occuring in one second is called frequency.

Answer 2

Explanation:

b) A time period (denoted by 'T' ) is the time taken for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the time period of the wave decreases. The unit for time period is 'seconds'.

a) Oscillation is defined as the process of repeating variations of any quantity or measure about its equilibrium value in time. Oscillation can also be defined as a periodic variation of a matter between two values or about its central value.
