It’s divided into three general regions, called UVA, UVB, and UVC. And since UV is the focus of this article, let’s zoom in on just that part of the spectrum. You can do more damage with ultraviolet rays than with visible light, for example. Using the equation behind my smart-ass answer, we can see that higher frequency also means higher energy. Here’s a nice illustration of the electromagnetic spectrum from NASA showing that relationship and more. Higher frequency means shorter wavelength. Wavelength and frequency are inversely proportional. You can convert between the two using its speed, which, for electromagnetic radiation, is the speed of light. Ultraviolet radiationĮlectromagnetic radiation can be described by its wavelength or its frequency. Then we’ll answer the question about whether UV lamps might help your IAQ. Let’s begin by understanding the first part first, UV radiation. UV lamps are sold as an aid to improving indoor air quality (IAQ), and lately that includes killing the coronavirus that may be in the air in your home. This is important in understanding ultraviolet (UV) radiation and its use in buildings. So the higher the frequency, the higher the energy of the photons. That’s the energy of photons for electromagnetic radiation with frequency, ν. E/h = ν, where E is energy, h is Planck’s constant, and ν, the Greek letter nu, is frequency. It really does bear on the subject of this article. Some of you know where my answer came from, but let me explain. They’d look at me like I just stepped out of a flying saucer, and I’d explain the “joke.” Hahaha! Then we’d both laugh our heads off. When I learned the basics of quantum physics, for example, I had a clever/annoying answer for anyone who asked me, What’s new? E over h, I’d respond. I used to be a smart-ass who would say things I thought were clever but really were just annoying.
