Electromagnetic waves can transfer energy without a(n). a) medium. b) electric field. c) magnetic field. d) change in either a magnetic or an electric field.

A: medium

Explanation:

Energy can be transferred in many different ways, and one of those ways is through electromagnetic waves. This form of energy transfer is also known as radiation.

When an object produces energy that it needs to release, it can be released in three ways. Conduction, convection or radiation. The one form of thermal energy transfer, is via radiation, because it does not need a medium for it to travel through.
