In physics , electromagnetic radiation EM radiation or EMR refers to the waves or their quanta , photons of the electromagnetic field , propagating radiating through space, carrying electromagnetic radiant energy. Classically , electromagnetic radiation consists of electromagnetic waves , which are synchronized oscillations of electric and magnetic fields. In a vacuum, electromagnetic waves travel at the speed of light , commonly denoted c. In homogeneous, isotropic media, the oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. The wavefront of electromagnetic waves emitted from a point source such as a light bulb is a sphere. The position of an electromagnetic wave within the electromagnetic spectrum can be characterized by either its frequency of oscillation or its wavelength.
