Question

Define amplitude and frequency.

Answer 1

Amplitude

1. It is the maximum displacement of the bob in a pendulum from its mean position.
2. It is the distance between the mean position and one of the extreme positions of the bob.

Frequency

1. It is the number of oscillations made by the pendulum in one second.
2. It is denoted by $norf$.
3. The unit of frequency is $hertz\left(Hz\right).$
4. Frequency is reciprocal of the time period. $n=\frac{1}{T}$
