Perhaps this could also be attributed to BBC News?

What are electromagnetic waves?
An electromagnetic wave is energy that consists of related magnetism
and electricity.
An electromagnetic wave can be thought of as an oscillating electric
force travelling through space accompanied by an oscillating magnetic
force in a plane at right angles to it.

Hi List,student
In discussion with my students about different forms of energy , a
asked whether light (EM) is a form of energy at all, or whether it
really
just a mode of transmission of potential energy. This was a goodquestion,
with the ensuing debate entertaining the class. Heck, what is light?
