The loudness or softness of a sound is determined by:
Amplitude
Wavelength
Time period
Frequency
The loudness or softness of a sound is determined by amplitude. The loudness of the sound varies with the square of its amplitude.
Name the quantity from below which determines the loudness of a sound wave :
(a) Wavelength
(b) Frequency, and
(c) Amplitude.
When we change a feeble sound to a loud sound, we increase its :
(a) frequency
(b) amplitude
(c) velocity
(d) wavelength
