Q44 A coherent parallel beam of microwaves of wave length 0 5 mm falls on a Young s double slit appa ratus The separation between the slits is 1 0 mm The intensity of microwaves is measured on a screen placed parallel to the plane of the slits at a distance of 1 0 m from it as shown in the figure 1998 30 d 1mm D 1 0m Y a If the incident beam falls normally on the double slit apparatus find the y coordinates of all the in terference minima on the screen b If the incident beam makes an angle of 30 with the x axis as in the dotted arrow shown in figure find the y coordinates of the first minima on either side of the central maximum
