Light is all around us. Vision is our dominant sense, and we are richly rewarded with a palette of colors from red to violet. Our eyes do not detect the l energy, longwavelength infrared (IR) radiation, but we know it exists from d cussions of war applications and televised images of guided weapons targets. Our eyes do not detect the higherenergy (above visible light energies) and shorterthanvisiblewavelength ultraviolet radiation, and yet we know it is there from the sunburn we receive in Arizona. We also know that window glass can block ultraviolet rays so we dont get a burn while driving with the windows rolled up. We know about radio waves from the little boxes that talk to us and xrays from the dentist office. These waves and rays belong to the same family of light, often called photons (from the Greek photos, light), that describes the spectra of electromagnetic radiation over 10 orders of magnitude from very lowenergy dio waves to very highenergy xrays and gamma rays.
