Question

3. How is the transfer of energy different in electromagnetic waves

compared to mechanical waves?

Answer 1

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

Answer 2

Electromagnetic waves are produced by the vibration of charged particles. ... A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum. Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave.
