Question:
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?" d jones

Replies:
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.
