Question

state two laws of vibration st​

Answer 1

Answer:

(1) Law of length : The fundamental frequency of vibrations of a streched string is invessely proportional to its vibrating length, if the tension and mass per unit length are kept constant. <br> (2) Law of tension : The fundamental frequency of vibrations of a stretched string is direactly proportional to the square root of the applied tension, if the length and mass per unit length are kept constant. <br> (3) Law of mass : The fundamental frequency of vibrations of a stretched is inversely proportional to the square root of its mass per unit length, if the length and tension are kept constant.

Explanation:

The fundamental frequency of vibration of a stretched string or wire is given by <br>
