Explanation:
1. wave form
noice- the wave of noise is irreregular
music- the wave of music is regular
2. frequency
noice- as wave form is irregular then frequency is also irregular means not definite.
music- as wave form is regular then it's frequency is also regular means definite.
3. nature of vibration
noice-In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain.
music-The basic nature of sound as a physical vibration – one that requires a medium of transfer such as air, a solid or a gas – is an example of oscillatory behaviour.
