Light of wavelength λ passes through a single slit of width a. The diffraction pattern is observed on a screen that is very far from from the slit. Which of the following will give the greatest increase in the angular width of the central diffraction maximum?
(a) It cannot be changed Reduce the slit width to a/2 and increase the wavelength to 2λ (b) Increase the slit width to 2a and reduce the wavelength to λ/2 (c) Increase the slit width to 2a and increase the wavelength to 2λ(d) Reduce the slit width to a/2 and reduce the wavelength to λ/2(e) It cannot be changed
