1. Determine the wavelength of a monochromatic beam of light that impinges on a double slit with a slit separation of 2.80 mm. Bright fringes are produced on a screen 1.20 m from the double slit. the brights are separated by .024m.
2. What approximation is required to derives the equation that defines the Young's 2 slit experiment?
3. What is the ratio of slit separation to wavelength for a 3rd order fringe that is located at a 12 degree angle?
4. Consider a thin film with n=1.42, immersed in air, and a light of 650nm wavelength. Determine the thickness of film that will create reflected light that constructively interferes.
5. Determine the slit width that produces a diffraction pattern with the 2nd dark fringe at 6.2mm from the central fringe. the screen distance is 1.25m and the light wavelength is 600nm.
6. Determine the angle for the first order maximum of a 20,000 lines/cm diffraction grating and light wavelength at 550 nm.
7. Determine the index of refraction of glass that is struck by unpolarized light at 53.8 degree and resulting in a fully refected beam.( Brewster angle).
