Question

Number of oscillation per second of vibrating object is called its time period

Answer 1

yes it is called as time period

Answer 2

False.

The number of oscillations per second of a vibrating object is known as its frequency.

The time period of an object is the time that is taken to complete an oscillation.

The frequency and time period of an object is always inversely proportional to each other, i.e., T = 1/f.

Both these sound parameters are fundamentals of Physics and many new laws revolve around them.
