Time period

Q.

The SI unit of time period is _____.

Q.

Time period of a sound wave is defined as:

1. time between the occurrence of two peaks

2. time between the occurrence of two valleys

3. time taken by two consecutive peaks/valleys to cross a fixed point

4. all of the above

Q.

The time period $\left(T\right)$ of a vibrating body of frequency $(f=100Hz)$ is:

1. 100 s

2. 10 s

3. 0.1 s

4. 0.01 s

Q.

Time period (T) is related to frequency (f) as:

1. $T=f$

2. $T\times f=0$

3. $T\times f=v$
   where v: speed of sound wave

4. $T=\frac{1}{f}$

Q. The time required to produce one complete wave is called time period.

1. True
2. False
