light interference

想問下塊Grating既厚度會唔會影響個light interference實驗結果:smile_41::smile_41::smile_41:


同埋點解D fringe 中間果part係最光:smile_41:

If the slits are not narrow enough, both single-slit and double-slit diffraction would occur simultaneously. The resulting interference pattern will be the sum of both, in which the central fringe has the highest intensity.

For an "ideal" double-slit experiment, all fringes should have the same intensity.
