How does the speed of sound change with change in (i) amplitude and (ii) wavelength, of sound wave ?
(i) Speed of sound does not change with a change in amplitude.
(ii) Speed of sound decreases with a decrease in wavelength and vice-versa.
Name the characterstic of the sound affected due to a change in its ( i) amplitude, (ii) wave form, and (iii) frequency.
(i) Two sound waves having the same amplitude but different frequencies.
(ii) Two sound waves having the same frequency but different amplitudes.
