Determination of wave-length laser during the leadthrough of experiment in laboratory terms by means of diagnostics of laser ray through the unique diffraction of cut. Analysis of results: length of fringe, areas and interrelation between factors.

The bigger the aperture, the smaller the ratio between the fringes and the distance between the projection plate and slit mask, so the fringes will become smaller, as the This formula can be simplified: IMG_6e15458a-c40b-441c-9a60-5e274751b77a According to the found ratio, the wavelength can be calculated through multiplying the fringe length by the aperture length ad dividing it by the distance between the slit and the projection plate. Dependent: The resultant diffraction pattern-it will vary with every change that is made with the distance between the aperture and projection plate. The wavelength-the same laser pointer will be used for all the trials; the frequency and The slit width for each particular trial; 3 slits will be used, each of them has a particular wave length. The distance between the slit and the projection plate; for each trial, the diffraction window and projection plate will be held constant. Take a ruler and measure the average width of the fringes on the projection plate/ and measure the distance between the last and first maxima, counting the fringes.
