Question 5 When we change feeble sound to loud sound we increase its (a) frequency (b) amplitude (c) velocity (d) wavelength
(b) amplitude Because the intensity of sound waves is directly proportional to the square of the amplitude.
When we change a feeble sound to a loud sound, we increase its :
(a) frequency
(b) amplitude
(c) velocity
(d) wavelength
When we change a feeble sound to a loud sound, we increase its
(a) frequency (b) amplitude (c) speed (4) timbre
When we change feeble sound to loud sound, we increase its:
