Diffraction and Interference . Object: To observe constructive and destructive interference of light using a diffraction grating and a single slit, and to use this phenomenon of interference to measure the wavelength of light. LASER SAFETY. A low wattage laser will be used during this lab. Before connecting the power supply to the laser, filexlib. Interference The theories behind interference is quiet similar to that of diffraction. Instead of using single slit for laser to pass through, double-slit is used for interference experiment. Same, we use the terminology in the previous experiment to denote the parame- ters, and we use d to represent the double slit separation.

11. INTERFERENCE AND DIFFRACTION 1. Monochromatic light from a narrow slit illuminates two narrow slits 0.3 mm apart producing an interference pattern with bright fringes 1.5 mm apart on a screen 75 cm away. Find the wavelength of the light. How will the fringe width be altered if i) the distance of the screen is doubled
prism, i.e., the dispersion (frequency dependence) of the refractive index. However, the use of diffraction or interference phenomena provides much better wavelength selection because these exploit the wave nature of light. Diffraction and interference are closely related phenomena; in fact, diffraction can be considered interference with
13: Interference and Diffraction Last updated Jul 20, 2021 12.6: Chapter Checklist 13.1: Interference Howard Georgi Harvard University A "beam" of light is very familiar. A laser pointer, for example, produces a pattern of light that is almost like a transverse section of a plane wave. But not quite. The laser beam spreads as it travels.
Interference and Diffraction . 14.1 Superposition of Waves Consider a region in space where two or more waves pass through at the same time. According to the superposition principle, the net displacement is simply given by the vector or the algebraic sum of the individual displacements. Interference is the

PHYS 102 - Discussion 13 Group activities Diffraction and Interference Lesson goals At the end of your discussion section, you should be able to: • Compare interference and diffraction. • Analyze and predict interference & diffraction patterns. Preparation instructions • Read the instructions for the questions very carefully. Most of them do not ask for calculations but require you to
that produces single slit diffraction. As you will observe in this experiment, the real interference pattern will have interference pattern enveloped in diffraction pattern with evenly-spaced narrower bright fringes grouped in a few broader bands with decreasing intensity on both sides. The broader bands are because of the single slit diffraction.
