Question

2. Define the following.
(i) Frequency of vibration
(ii) Amplitude of vibration
(iii) Time period​

Answer 1

Answer:

1. Frequency : Number of oscillations made by a wave in one second is known as its frequency
2. Amplitude : The maximum displacement of a wave on either side of its mean position is called amplitud
3. Time period : Time taken to complete one vibration is called Time period

Answer 2

Answer:

Time period

A time period (denoted by 'T' ) is the time taken for one complete cycle of vibration to pass a given point. ... The unit for time period is 'seconds'. Frequency and time period are in a reciprocal relationship that can be expressed mathematically as: T = 1/f or as: f = 1/T.

frequency of vibration

The number of vibrations or oscillations made in one second is called the frequency of vibration. The unit of frequency of vibration or oscillation of a vibrating object is hertz. When an object makes one vibration per second its frequency is said to be 1 hertz. ... Time period is equal to the reciprocal of frequency.

Amplitude of vibration

Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.
