1.Light of wavelength 613 nm is incident on a long, narrow slit. Find the angle of the first diffraction minimum for each of the following widths of the slit.
1)(a) 1 mm
2.) 0.1 mm
3.) 0.01 mm
2.Suppose that the central diffraction maximum for two slits has 33 interference fringes for some wavelength of light. How many interference fringes would you expect in the diffraction maximum adjacent to one side of the central diffraction maximum?
