The adjacent diagram shows three different modes of vibrations P, Q and R of the same string. (i) … ) State the ratio of wavelengths…
(i) Vibration R as its amplitude is high as loudness ∝ A2
(ii) Sound of string ‘P’ will have maximum shrillness as its frequency is maximum.
Pitch ∝ frequency.
(iii) λP : λR = 3 : 1
