 In 1803 , Young 's interference experiment played a major role in the general acceptance of the wave theory of light . If white light is used in Young 's experiment , the result is a white central band of constructive interference corresponding to equal path length from the two slits , surrounded by a symmetrical pattern of colored fringes of diminishing intensity . In addition to continuous electromagnetic radiation , Young 's experiment has been performed with individual photons , with electrons , and with buckyball molecules large enough to be seen under an electron microscope .
