He proposed the new rays were a new form of light and won the Nobel Prize for his discovery. significance

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.
