    Sir but actually sound travels fastest in solids because the particles are tightly packed when a molecule or particle vibrates it causes the particles next to them to vibrate as well hence the particles in solids are held in a framework sound spreads quickly as compared to liquids and gases in which particles are far from each other.

    • @prardhanab9102
      @prardhanab9102 Год назад +3

      It is like when frequency increases then pitch also increases this is called directly proportional another example for this is when frequency decreases pitch also decreases ( basically together)

    • @prardhanab9102
      @prardhanab9102 Год назад +3

      And for inversely proportional it means basically the opposite from directly proportional such as if A is going up and B is going in the opposite direction ( down ) then its inversely proportional
      ...hope this was helpfull😊
