Does velocity of sound waves depends on amplitude.how?
The amplitude of sound wave has nothing to do with velocity (phase) of sound waves. Thus, even mention of loudness, for amplitude or energy of sound waves, is not warrented here. Try making a sine wave of given wavelength LAMDA and amplitude ‘A’. The dual peaks of ‘A’ indicate the pressure which the medium exerts on characterstic frequency (source producing that wave) to change polarity (returing towards x-axis) on either sides. You can increase/decrease the ‘A’ without changing LAMDA on graph, but this will be done by different medium, whereas the source of wave (frequeny) is still the same. Please note that frequeny of wave n = (v / Lamda) is universal for the material that produces that sound – say a siren. This sirun sound may pass through various mediums (refractive indices) one after the other. n remains constant because source (sirun) is not undergoing change of mediums – and that property forces the wave to alter the ratio of “V’ and ‘Lamda’ in such a way that it always produce
