Adiffraction 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 (q= 0°) and one on either side of it at q=+/-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

After the seventh month of a 12-month loan: the numerator is: {(n + 11) + (n + 10) + (n + 9) + (n + 8) + (n + 7) + (n + 6) + (n + 5)} = , and the denominator is: {(n) + (n + 1) + + (n + 11)} = . therefore, the fraction is numerator/denominator (to the nearest tenth) = %
