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).

(B) I Woy The figure shows two patterns projected on screens from shining a laser through a double slit apparatus. The black spots are the light from the laser. What could be the cause of the difference we see between setup A and setup B? Setup A has larger slit spacing or uses a laser with larger wavelength. Setup A has smaller slit spacing or uses a laser with smaller wavelength. Setup A has smaller slit spacing or uses a laser with larger wavelength. Setup A has larger slit spacing or uses a laser with smaller wavelength.
