Looking under a microscope at a smaller part of the disc we would see something very similar to a diffraction grating: very fine, regularly spaced lines. WebDiffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture. The diffracting object or aperture effectively becomes a secondary source of the propagating wave. Italian scientist Francesco Maria Grimaldi coined the …

Webpassing through the grating. Since the only unknown is this equation is the slit spacing d you can easily solve for it. Although a CD is not really a diffraction grating, after all the light bounces off of the CD, it does not pass through it, the CD acts like a diffraction grating because the reflected light undergoes constructive and destructive WebThe grating element calculations from the diffraction pattern will agree very well with the spacing measured from analyzing the AFM images.
