Basic Electromagnetic Wave Properties - Electromagnetic radiation is characterized by a broad range of wavelengths and frequencies, each associated with a specific intensity (or amplitude) and quantity of energy.
Low energy photons (such as radio photons) behave more like waves, while higher energy photons (such as X-rays) behave more like particles. The electromagnetic spectrum can be expressed in terms of energy, wavelength or frequency. Each way of thinking about the EM spectrum is related to the others in a precise mathematical way. Scientists represent wavelength and frequency by the Greek letters lambda (Î») and nu (Î½).
