tem 10 Coherent light from a sodium-vapor lamp is passed through a filter that blocks everything except for light of a single wavelength. It then falls on two slits separated by 0.470 mm. In the resulting interference pattern on a screen 2.24 m away, adjacent bright fringes are separated by 2.76 mm Part A What is the wavelength of the light that falls on the slits? λ = OF ID ΑΣΦ Submit My Answers Give Up ? nm Provide Feedback Continue
2. Red laser light (X=680 nm) is incident on two narrow, closely-spaced slits. The resulting pattern of bright and dark fringes is projected on a screen, and the centermost bright fringes are seperated by 2.0 cm. If the red laser is replaced with a green (A=500 nm) one, how would the spacing of the centermost fringes change? A. The centermost bright fringes will remain 2.0 cm apart B. The centermost bright fringes will get closer together C. The centermost bright fringes will get farther apart D. No bright fringes would be visible
A flat screen is located 0.67 m away from a single slit. Light with a wavelength of 510 nm (in vacuum) shines through the slit and produces a diffraction pattern. The width of the central bright fringe on the screen is 0.051 m. What is the width of the slit? Number i Units
beam of monochromatic light is incident on a single slit of width 0.560 mm. A diffraction pattern forms on a wall 1.20 m beyond the slit. The distance between the positions of zero intensity on both sides of the central maximum is 2.36 mm. Calculate the wavelength of the light. nm A helium-neon laser (A = 632.8 nm) is used to calibrate a diffraction grating. If the first-order maximum occurs at 20.1 Degree , what is the spacing between adjacent grooves in the grating? (In this problem, assume that the light is incident normally on the gratings.) pm White light is spread out into its spectral components by a diffraction grating. If the grating has 1 980 grooves per centimeter, at what angle does red light of wavelength 640 nm appear in first order? (Assume that the light is incident normally on the gratings.)
A flat observation screen is placed at a distance of 4.7 m from a pair of slits. The separation on the screen between the central bright fringe and the first-order bright fringe is 0.035 m. The light illuminating the slits has a wavelength of 495 nm. Determine the slit separation. Number i Units

In a Young's double slit experiment the wavelength of light is ?λ, separation between the slits is ?a and the distance to the screen is ?D. Give an expression for the interference fringe width ?w on screen if ?≫?D≫a. For Greek letters such as ?λ use the text equivalent - e.g. "lambda" (without the quotes, e.f. for ??Dλ use D*lambda).
