Blue light of wavelength A passes through a single slit of width dand forms a diffraction pattern on a screen. If we replacethe blue light by red light of wavelength 2A, we can retainthe original diffraction pattern if we change the slit width(a) to d/4.(b) to d/2.(c) not at all.(d) to 2d.(e) to 4d.
