  • B. Wilhelm Rontgen
  • C. Isaac Newton
  • D. Guglielmo Marconi
Correct Answer: Option C - Visible radiation was discovered by Isaac Newton. The wavelength of visible light ranges from 390-780 nano metres (nm). Its production source is the incandescence things such as sunlight, flames, electric bulb, arclamp and the radiation produced by molecules of ionized gases when elated. Due to this light, we can see the things.
