Homework Help: Physical optics

  1. Apr 3, 2006 #1
    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.

    I thought maybe I could help, but my physics textbook exploded while I was looking into the details surrounding this question. True story.
