hey so i'm having a lot of trouble on this section of physics. the question i'm on is: Green light (546nm) strikes a single slit at normal incidence. what width slit will produce a central maximum that is 2.3 cm wide on a screen 1.42m from the slit? I've been trying to manipulate Wsin(0)=wavelength and y=Ltan(O), but i can't get anything to work. I appreciate any help.
