Question:
How was full spectrum light discovered?
Best Answer - Chosen by Asker:
if you mean in a scientific sense, then one thinks of Isaac Newton, arguable the greatest scientist who ever lived. we remember Newton for several fundamental discoverys -- the laws of motion, the force of gravity, calculus, to name three.
significantly, Newton was always interested in the nature and composition of light. Wikipedia says this: "In optics, he invented the reflecting telescope and discovered that the spectrum of colors observed when white light passes through a prism is inherent in the white light and not added by the prism ... Newton notably argued that light is composed of particles."
This last point was astonishing at the time (late 1600s), and it was taken up again by Einstein (around 1900), stimulating him to produce the theory of the photon.
BTW, Einstein won his Nobel prize for the theory of the photon, not for his theories of relativity!
good luck!
