Question

Yellow Green Blue All the colors give the same resolving power. The Diffraction Grating 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 (theta = 0 degree) and one on either side of it at theta = plusminus 50 degree. 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. only red fringes at 0 degree and plusminus 50 degree only yellow fringes at 0 degree and plusminus 50 degree only orange fringes at 0 degree and plusminus 50 degree an orange fringe at 0 degree. yellow fringes at plusminus 50 degree, and red fringes farther out an orange fringe at 0 degree, yellow fringes at plusminus 50 degree and red fringes closer in

Explanation / Answer

when , the diffraction grating is illuminated with yellow light.the doffraction pattern seen on a viewing screen consisting of threeyellow bright firnges , one at the central maximum and one on either side of it at = ± 50 deg . then grating is simultaneously illuminated with red light .where a red and yellow fring overlap an orangne fringe is produced .the nwe pattern consisting of an orange fringe at 0 deg , yellow frings at ± 50 deg and red fringe farhter out ,Here fringes are formed on the the basis of their wavelenght's order. Hence , Among the given option (d) is correct
