A horizontal beam of laser light of wavelength 501 nm passes through a narrow slit that has width 6.20×10−2 mm . The intensity of the light is measured on a vertical screen that is 3.00 m from the slit. Use the result of part A to estimate the width of the central diffraction maximum that is observed on the screen. Express your answer to two significant figures and include the appropriate units.

T/F: When light passes through two or more narrow slits, an alternating dark and bright pattern is observed on a screen because of reflection of light. T/F: Optical fibers work because of total internal reflection of light. T/F: You see colors in a rainbow because of interference of light. T/F: A light ray bends when it goes from one medium to another because of refraction. T/F: When you look into a pool of water, the depth looks less than it...

When monochromatic light passes through a narrow slit it produces on a screen a diffraction pattern consisting of bright and dark fringes. The intensity of the bright fringes, I, as a function of can be calculated by: where Where is the light wave length and a is the width of the slit. Plot the relative intenstiy I / Imax as a function of for -20o <= <= 20o. Make one plot that contains three graphs for the cases a =...

Question 8 You are conducting an experiment on the diffraction of light through a single narrow slit. You have situated your viewing screen a distance of 1 m away from the slit, with blue light of 450 nm and the slit width is 2.4um. You observe a normal interference pattern with a bright central maximum. What happens to the central maximum if you switch out the 2.4um single slit for a 4.8um single slit? No change occurs to the central...
