Answer: The correct answer is "Electromagnetic waves travel slower than sound waves".

Explanation:

Sound wave is a longitudinal wave. The particles of the medium oscillate to the parallel to the direction of the propagation of the wave. It needs a medium to travel.

It can travel in solid, liquid and gas.

Sound wave travels fastest in the solid medium. It travels slowest in the gaseous medium.

Light wave is an electromagnetic wave. It does not need any medium to travel. It can travel in vacuum. It travels with the speed of the light. It is transverse in nature.

Therefore, the correct option is "Electromagnetic waves travel slower than sound waves".
