WebOn 22 February 1801, Johann Wilhelm Ritter discovered UV radiation in Jena. In general, this achievement is less well known than his work on galvanism. Ritter was the …
WebIn 1801 Ritter made the startling discovery that silver chloride, which decomposes in the presence of light, is more rapidly decomposed when exposed to the invisible, theretofore unknown radiation beyond the violet end of the spectrum. Ritter devoted most of his efforts to the study of electricity and electrochemistry. Webnot only because it led to the discovery of infrared light, but also because it was the fi rst time it was shown that there were forms of light we cannot see with our eyes. As we now know, there are many other types of electromagnetic radiation (“light”) that the human eye cannot see (including X-rays, ultraviolet rays and radio waves).
