Which out of the following characteristic determines the loudness of sound wave?
Pitch
Amplitude
Frequency
Wavelength
The amplitude of a sound determines the loudness of a sound. Larger the amplitude more is the loudness.
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
Question 5 When we change feeble sound to loud sound we increase its (a) frequency (b) amplitude (c) velocity (d) wavelength
