WebThe grating element calculations from the diffraction pattern will agree very well with the spacing measured from analyzing the AFM images. The spacing of tracks in a DVD is about half as that in a CD giving it twice as many tracks per mm. This accounts for about a two … WebThe analysis of a diffraction grating is very similar to that for a double slit (see Figure 27.19).As we know from our discussion of double slits in Young's Double Slit Experiment, light is diffracted by each slit and spreads out after passing through.Rays traveling in the same direction (at an angle θ θ relative to the incident direction) are shown in the figure.

WebSounds like the setup has the correct order. I think what you need to consider is that the light spreads after the grating and the whole spectrum should fit the lens, otherwise you'll miss part of it. No interference should be present in the readings. Additionally, if the incoming light is not collimated, you might need a curved mirror or lens. Webexamples of diffraction are those involving light; for example, the closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar rainbow pattern we see when looking at a disk. Diffraction in the atmosphere by small particles can cause a bright ring to be visible around a bright light source like the sun or the moon.
