Experiment 3 1. Student passes 633 nm laser light through a narrow slit and observe the diffraction pattern on a screen 7.00 m away. The distance on the screen between the centers of the first minima on either side of the central bright fringe is 35.0 mm. (a) How wide is the slit? (b) The intensity at the center of the pattern is lo. What is the intensity at a point on the screen 3.80 mm from the center of...
A double slit interference pattern uses red light with lambda = 650 nm. The slits are 1 mu m apart. What is the angle theta for the first order bright fringe?
Light from a laser passes through a pair of slits and forms a pattern on a screen 4 meters from the slits. The slits are 50?m wide and are 0.1mm apart. a) If the wavelength of the laser is 650 nm, sketch the pattern made on the screen. b) Calculate the spacing between fringes and the width of the central maximum. c) A wedge of material is slipped in front of one slit until the central bright fringe disappears (a...
Helium-neon laser light of wavelength 353 nm is sent through a 0.459 mm wide single slit. What is the width of the central maximum on a screen 1.22 m from the slit?
Helium–neon laser light (λ = 632.8 nm) is sent through a 0.250-mm-wide single slit. What is the width of the central maximum on a screen 2.00 m from the slit? mm
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.
