Name the characterstic of the sound affected due to a change in its ( i) amplitude, (ii) wave form, and (iii) frequency.
What change do you expect in the characteristics of a musical sound if:
i) its frequency is increased ii) its amplitude is increased
When we change a feeble sound to a loud sound, we increase its
(a) frequency (b) amplitude (c) speed (4) timbre
(i) Two sound waves having the same amplitude but different frequencies.
(ii) Two sound waves having the same frequency but different amplitudes.
How does the speed of sound change with change in (i) amplitude and (ii) wavelength, of sound wave ?
