Electromagnetic (EM) waves differ profoundly from other kinds of waves in that they need no material medium — they can carry energy through a vacuum. EM waves are regular, periodic disturbances in electric and magnetic fields in space. Most EM waves can also travel through some material substances, with the substance acting as no more than a penetrable barrier. This chapter discusses the following: the nature of EM waves; how radiant energy is generated; and how radiant energy is dissipated.

Keywords: electromagnetic waves; radiant energy; energy dissipation; energy generation
