In a single slit diffraction pattern, how does the angular width of central maximum change, when:-
(a) The slit width is decreased.
(b) Distance between the slit and screen is increased.
(c) Light of smaller visible wavelength is used?
Justify your answer in each case. 
Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory.
