Question

Electromagnetic waves can travel with no medium because it has tiny electric and magnetic fields that vibrate instead any of material vibrating. When light travels through a medium like air electric and magnetic fields are the ones still vibrating but the particles in the air actually slow down the light. You can consider light as a particle with some energy that normally travels through a vacuum without a medium but when it reaches a medium, it will either be slowed down or brought down to a complete stop depending on the type of medium because the light particles energy will be absorbed by t
