Question

define the following terms.also write their SI unit.
a.Amplitude
b.time period
c.Frequency​

Answer 1

Answer:

amplitude- the maximum displacement of a vibrating body in a central position,is called amplitude. its SI unit is metre

B. The unit for time period is 'seconds'. Frequency describes the number of waves that pass a fixed place in a given amount of time. ... The hertz measurement, abbreviated Hz, is the number of waves that pass by per second i.e SI unit is hertz

C. Frequency describes the number of waves that pass a fixed place in a given amount of time. ... The hertz measurement, abbreviated Hz, is the number of waves that pass by per second i.e SI unit is hertz.

Answer 2

Explanation:

HEY MATE ..

1. AMPLITUDE : Normally the symbol A is used to represent the amplitude of a wave. The SI unit of amplitude is the metre (m). Amplitude. The amplitude of a wave is the maximum disturbance or displacement of the medium from the equilibrium (rest) position.
2. Time Period (T) : Time taken to complete one vibration is called Time period , i.e from A to B.
3. Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. Frequency is measured in units of hertz (Hz) which is equal to one occurrence of a repeating event per second.
