b. sound waves
Sound waves need to travel through a medium such as a solid, liquid, or gas. The sound waves move through each of these mediums by vibrating the molecules in the matter. This means it isn't an electromagnetic waves but it is a wave, an example of the difference, all electromagnetic waves can travel in a vacuum at the universal speed limit, this is 299 792 458 m/s.

Sound waves are longitudinal waves. All are the examples of Electromagnetic waves except the sound wave.

EM Waves:

EM waves are transverse waves means the propagation of the wave is the perpendicular the the wave oscillation.

Sound waves:

These are the longitudinal waves because the propagation of the wave is parallel to the vibration of particles.

  • It needs medium like air and water.
  • Its speed is very lesser than speed of EM wave.

Therefore, all are the examples of Electromagnetic waves except the sound wave.
