Question

How are electromagnetic waves different from sound or water waves?

Answer 1

Explanation:

Electromagnetic waves are different from sound or water waves in such a way that water and sound waves are called mechanical waves that requires a material medium for their propagation.

Electromagnetic waves do no require a material medium for propagation.

• Electromagnetic waves are carried or transported by radiation and this can be passed through vacuums and different other materials.
• But mechanical waves such as water and sound waves requires a material medium for their propagation.
• They cannot pass through a vacuum.
