I already know that visible light is only a tiny fraction of the electromagnetic spectrum, and just after that comes UV radiation, since its wavelength is shorter and thus frequency is higher. My question is: if you can ONLY see visible light, then why can you often see UV light as purple? Isn’t it supposed to be invisible? I’m referring to those commercial torches that emit UV (and purple) light.
In: Physics
its in their name ” Ultra Violet” while the light you actually care about is not actually visible some of it will and this visible part of it will be at the edge of the violet spectrum of visible light . we cant avoid this because its very difficult ot have a bulb that only emits one type of radiation.
