Homework Help: Diffraction of light

    The brightness of the colour is proportional to its amplitude?
    I can understand why the middle of the screen is the brightest, but in my mind, I think there should be only one area which is bright for a single-slit.

    The diffraction of a light beam is really different from that of a water wave, isn't it?
