Question

define a) amplitude b) frequency

Answer 1

Explanation:

amplitude= the the amplitude of a period is variable is a measured of its change in a single period. there there are various definition of amplitude which are all functions of magnitude of the difference between the variables extreme values. in older text the the phase of a period function is sometimes called the amplitude.

frequency= frequency describes the number of waves that part of fixed place in a given amount of time. so if the time it takes for a wave is 1/2 second the frequency is 2 per second. if takes 1/100 of an hour the frequency is 100 per hour.

hope this will helpful for you.

Answer 2

a)Amplitude: the maximum displacement of a vibrating body from its mean position is called amplitude.

b)Frequency: The number of oscillations produced by a vibrating body in one second is called frequency. It is expressed in a unit called hertz (Hz).
