(a)Which of the following quantity determines the loudness of a sound wave?
(i)Wavelength
(ii) frequency and
(iii) amplitude
(b)How is loudness related to the quantity mentioned in the above part (a)

(a) The loudness of a sound wave is determined by its amplitude. A loud sound has a higher amplitude, while a quiet sound has a lesser amplitude.

(b) The amplitude is proportional to the square of the loudness.
