In two or more complete sentences, describe two differences between electromagnetic waves and mechanical waves,

Electromagnetic waves travel in vacuum where as mechanical waves don't. The mechanical waves need a medium like water, air, or anything for it to travel. While mechanical waves are cause by wave amplitude and not by frequency, electromagnetic waves are produced by the vibration of the charged particles.

Explanation:

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

the inner core.
