Explanation:
Light is a transverse wave because its components vibrate perpendicular to the direction of propagation.It has an electric and a magnetic property , so it is EM wave which is transverse in nature .
whereas, sound waves are longitudinal waves and <span>the particles of the medium move parallel to the direction that the pulse moves.
so, as sound waves moves parallel in direction of pulse so, it is affected by media , whereas light waves don't need medium to travel as they are em waves and tranversal in nature that is perpendicular motion.
hope it helepd :-)</span>
