when white light is separated into its colors. or
when white light is passed through a prism. or
when white light is passed through a diffraction grating.
You didn't give choices or we could pick the appropriate one but the above three are good answers although other answers may be possible too.Don't know what a diffraction grating is? Next time you have a chance pick up a CD and tilt it at an angle with the light shining on it. See all those colors. That CD is not a grating but it is functioning as a diffraction grating. The old time 78 rpm or 33-1/3 rpm phonograph records worked the same way but if you were born after 1980 or so you've probably never seen a phonograph record.
