Distinguish between sound waves and radio waves of same frequency, say 15kHz.

Explanation

Some of the points of distinction between sound waves and radio waves of same frequency are:
(i) Sound waves cannot travel through free space (vacuum), but radio waves can.
(ii) Velocity of sound waves in air `=332m//s`. Velocity of radio waves in free space `=3xx10^(8)m//s`.
(iii) Velocity of sound increases with rise in temperature. Velocity of radio waves is not affected by temperture.
(iv) Sound waves of frequencies ranging from 20Hz to 20kHz can be detected by the ear. Radio waves cannot be detected by the ear.
