Abstract: This lab helped us understand the physical and wave nature of light. In particular we learned the phenomena known as diffraction which causes the waves of light to be expanded into patterns that would not be expected otherwise. For instance an experiment showed us the diffraction patterns of a helium- neon laser which was pointed through a slit of known width. The width of the pattern shown on the wall changed with the varying widths of the slits that the laser was pointed through. This showed that there was an effect on the diffraction on the laser which directly corresponded to the slit width. Also we learned the effect on light waves when there were multiple slits. This also showed us how the different number of slits produced very different patterns with varying intensities and widths. There was also an experiment which helped us understand how a diffraction grating of non monochromatic light could be analyzed quantitatively. We were able to measure the angles of diffraction as well as different
