Question

How do Electromagnetic waves travel in vacuum?

Answer 1

Explanation:

1. Electromagnetic waves are non-mechanical waves.
2. Electromagnetic waves do not require a medium to propagate, they can easily pass through a vacuum.
3. Electromagnetic waves propagate outward in all directions from the source of the disturbance. Waves keep traveling until something interrupts them.
4. The farther a wave travels from its source, the more spread it is, and the fewer waves in a given area and the less energy is transferred.
