Due to the wave nature of light shines on a single slit will produce a diffraction pattern. Green light 505nm is shined on a slit with width 0.490nm.  a) find the width of the central maximum located 1.50 m from the slit in mm b) what is the width of the first order fringe in mm

Shown in the figure below is single slit experiment. Monochromatic light of wavelength A, = 6.7e-07 meters comes in from the left and passes through the slit. The result is a pattern of bright and dark bands visible on a screen at a distance D = 3.58 meters away from the slit. The distance between the central maximum and the first dark fringe is y, = 0.0442 meters. Single Screen Slit dark dark D Determine the width of the slit. a = meters If the light is changed to a different color Ànew 4.75e-07 meters, the diffraction pattern changes. What is the new location of the first dark band? ynew = meters WARNING: The drawing is not to scale.

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.)

Find the largest wavelength (in nm) of light falling on double slits separated by 7.5o µm for which there is a second-order maximum. nm Is this in the visible part of the spectrum? Yes No

Light of wavelength 575 nm falls on a double slit, and the first bright fringe of the interference pattern is seen at an angle of 13.0° from the central maximum. Find the separation between the slits. μm

When polychromatic visible light shines through a diffraction grating, the colors seen closest to the central maximum will: A. be visible as the lowest wavelength in the mixture B. be visible as the highest wavelength in the mixture C. be a mixture of the wavelengths present D. Always be white

a) What would be the angular position of the third dark fringe from the central maximum, if a 600nm light is incident on a double slit with a slit separation of 2µm? b) If the previous problems double slit also had a slit width of 0.5µm, would would the intensity fraction be at an angular position of 40 degrees?

Ex. 14 A certain fringe width is observed when green light of wavelength 5350 A.U. is used where the distance between the slit and the screen is 1.28 m. What should be the distance between the slit and screen if the red light of wavelength 6400 AU is used to get the same fringe width without disturbing the distance between the coherent sources ?ubonq
