and a frequency 
Many aspects of the interaction of electromagnetic radiation with matter require the use of quantum theory for their accurate description.
is: radiation consisting of fluctuating electric and magnetic fields that can propagate through space, or through suitable media, as electromagnetic waves characterized by a wavelength and a frequency Many aspects of the interaction of electromagnetic radiation with matter require the use of quantum theory for their accurate description.
is exemplified: by familiar phenomena such as visible light, radio waves and X-rays, which are all parts of the electromagnetic spectrum, corresponding to different wavelengths of electromagnetic radiation.
