A diffraction grating is illuminated with yellow light. The diffraction pattern seen on a viewing screen consists of three yellow bright fringes, one at the central maximum (θ = 0°) and one on either side of it at θ = ±50°. Then the grating is simultaneously illuminated with red light. Where a red and a yellow fringe overlap, an orange fringe is produced. The new pattern consists of _________.
(a) Only red fringes at 0° and ±50°
(b) Only yellow fringes at 0° and ±50°
(c) Only orange fringes at 0° and ±50°
(d) An orange fringe at 0°, yellow fringes at ±50°, and red fringes farther out
(e) An orange fringe at 0°, yellow fringes at ±50°, and red fringes closer in
