1.	The adjacent diagram shows three different modes of vibrations P, Q and R of the same string.(i) Which vibrations will produce a louder sound and why ? (ii) The sound of which string will have maximum shrillness ? (iii) State the ratio of wavelengths of P and R.
Answer» (i) R will produce louder sound because its amplitude is more than P and Q. (ii) The sound of P string will have maximum shrillness. (iii) The ratio of wavelength of P and R i.e., = 1 : 3

The adjacent diagram shows three different modes of vibrations P, Q and R of the same string.(i) Which vibrations will produce a louder sound and why ? (ii) The sound of which string will have maximum shrillness ? (iii) State the ratio of wavelengths of P and R.

Answer»

(i) R will produce louder sound because its amplitude is more than P and Q.

(ii) The sound of P string will have maximum shrillness.

(iii) The ratio of wavelength of P and R i.e., = 1 : 3
