Answer 1

☺ loudness and amplitude. The loudness of a sound is linked to the size of the vibrations which produces it

☺the number of vibration or oscillator per second is called frequency.

☺the time required to produce one complete oscillator is called time period

U hope it helpfull to you

Answer 2

1. Amplitude of vibration :-the maximum displacement or either side of main position in a medium.it is just characteristics of wave but loudness is characteristics of sound wave.

2. Frequency of vibration :- the no. oscillation per unit time is called as frequency. unit Hz

3. time period :- the time taken for one complete oscillation. T = 1/ frequency
