Difference among sound and light waves:
(i) For propagation of sound rays material phase is required but no material medium is needed for light waves.
(ii)Sound rays are longitudinal but light rays are transverse.
(iii) Wavelength of sound waves limits from 1.65 cm to 16.5 meter and for light wave it confines from 4000 Å to 2000 Å.
