Shortly afterward, Ritter also discovered the same effect, independently. … Webhe called calorifi c rays (derived from the Latin word for heat) beyond the red portion of the spectrum. He found that they were refl ected, refracted, absorbed and transmitted in a manner similar to visible light. What Sir William had discovered was a form of light (or radiation) beyond red light, now known as infrared radiation. (The prefi x "Ultraviolet" means "beyond violet" (from Latin ultra, "beyond"), violet being the color of the highest frequencies of visible light. Ultraviolet has a higher frequency (thus a shorter wavelength) than violet light.
