Explain the vibrations of streched string and state laws of streched string? |
|
Answer» am starting with the Laws of the stretched string :Laws of stretched string ⇒ The frequency of the string is inversely PROPORTIONAL to the length of the string .f ∝ 1 / l⇒ The frequency of the string is DIRECTLY proportional to the square root of the time PERIOD .f ∝ √t⇒ The frequency is inversely proportional to the square root of mass of the string .f ∝ 1 / √mHence f ∝ √t / ( l × √m )f = ( 1/2 √t ) / ( l × √m )More laws :⇒ The string if PLUCKED in the middle vibrates in one loop. The vibration is called principal note .⇒ The string if plucked at different ends produce different MODES of vibration.⇒ If l is the length of the string , then the different modes of vibration of the string if plucked at 2l , 2l/2 , 2l/3 will be 3 : 2 : 1 . |
