Electromagnetic Radiation & Energy
Date: 1993 - 1999
One of my students wants to know: "Do different types of
electromagnetic radiation actually have more or less energy; or is greater
energy a result of more waves passing a point per unit time?"
All forms of EM radiation are quantized in things called photons. The
energy of a photon is proportional to its frequency and inversely proportional
to its wavelength.
In energy-increasing order, the forms of EMR are: long wave radio, short wave
radio, microwave, infrared, visible, ultraviolet, x rays, and gamma rays.
