A diffraction grating is illuminated with yellow light. The diffraction pattern seen on a viewing screen consists of three yello
w 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
I don't know if I am right but I think this is the answer: If we write beaker with x and content with y then y=56.8/2=28.4 this is the content of one beaker so there are two beakers: 2x+28.4=180.4 2x=180.4-28.4 2x=152/2 x=76
