Question

How are electromagnetic waves different from mechanical waves?

Answer 1

Answer:

Electromagnetic waves can travel through empty space; mechanical waves can not  

Explanation:

The salient differences between electromagnetic waves and mechanical waves is that electromagnetic waves can travel through empty spaces but mechanical waves cannot.

Mechanical waves always requires a material medium for their propagation. No known mechanical waves can pass through an empty vacuum.

Electromagnetic waves on the other hand can pass through vacuum. They do not require a material medium for propagation.

This makes them unlimited in their form and mode of propagation.
