State the laws of vibrating strings.

(a) A string of length L is stretched between two rigid supports. It is plucked at the centre. What type of wave is formed in it? What is its frequency? (b) Obtain expressions for the frequency of higher harmonics of vibrations of a stretched string, (c) State the laws of vibrating string-

State the laws of reflection.

State the Law of Malus.

State the laws of static friction.

The frequency (n) of vibration of a string is given as n = (1)/( 2 l) sqrt((T)/(m)) , where T is tension and l is the length of vibrating string , then the dimensional formula for m is
