[@HeyFuinix]

Guysss important points 1.sound is produced by vibration of molecules 2.the vibration produces sound waves which travel through air 3. Maximum displacement from the mean position to other side is called amplitude 4. Time take to complete one oscillation is known as time period 5. Number of oscillation is known as frequency 6.humans have vocal cord in there larynx and there is a narrow slit present there which passes the air when we speak air vibrates and hence humans produces sound Learn karlo koi na koi ayega baaki book se padhlo and BEST OF LUCK GUYS 🔥🔥
