who was the first person to use a prism to split light?

Answer 1

It was Isaac Newton who first thought that prisms split colours out of colourless light. Newton placed a second prism such that a separated colour would pass through it and found the colour unchanged. He concluded that prisms separate colours. He also used a lens and a second prism to recompose the rainbow into white light.

Answer 2

Sir Isaac Newton discovered that when white light was shone through a piece of glass not necessarily a prism he found that the light came out different i.e the colours of the rainbow and thus advised the scientists of the day that light was in fact made up of different levels that were not clearly visible to the eye and that different colours reflected back its own range of the spectrum.

Answer 3

During the summer of 1666, Newton was displaced from his rooms in Cambridge to his parent's farm by the Great Plague. Using sunlight, formed into a narrow beam by his window shutters, Newton showed that a simple glass prism would split a beam of light into a series of colours extending from red through orange, yellow, green, blue, into indigo and violet. At least, that is the sequence of colours in the textbooks, but most people have trouble distinguishing indigo from violet, and violet from deepest red. However, this is an experiment that everyone has seen and the colours are the familiar hues of the rainbow, the sequence of colours of the visible spectrum. Their order is always the same and the sequence is sometimes remembered as ROYGBIV. Although Newton was unaware of it, beyond the red end of the spectrum is the infrared, detectable as heat, and beyond the blue are the invisible but energetic rays of ultraviolet light.

Answer 4

I think it was Isaac Newton. He proved something about rainbow and vibgyor
