You have a diffraction grating with two thin slits. You set it up outside in the sunlight.The white sunlight that passes through the two slits shines on a nearby wall. You seea bright white line, surrounded on the left and right by two rainbows. Explain whythis happens, including why there is a central bright line, and also explain the orderof the colors in the rainbow pattern (i.e., which is closest to the white spot, and whichis furthest). (Recall that the order of colors in a rainbow can be remembered by theacronym ROY G. BIV, where “T" stands for indigo).

Question

You have a diffraction grating with two thin slits. You set it up outside in the sunlight.
The white sunlight that passes through the two slits shines on a nearby wall. You see
a bright white line, surrounded on the left and right by two rainbows. Explain why
this happens, including why there is a central bright line, and also explain the order
of the colors in the rainbow pattern (i.e., which is closest to the white spot, and which
is furthest). (Recall that the order of colors in a rainbow can be remembered by the
acronym ROY G. BIV, where “T" stands for indigo).
