In a single slit diffraction experiment, the width of the slit is 3.1 x 10-5 m and the distance from the slit to the screen is 2.2 m. If the beam of light of wavelength 600 nm passes through the slit and forms a diffraction pattern on the screen, what is the linear distance on the screen from the center of the diffraction pattern to the first dark fringe? 6.3 cm 7.4 cm 4.3 cm O 8.5 cm
In an experiment using Young's slits, the distance between the center of the interference pattern and tenth bright fringe on either side of it is 3.44 cm and the distance between the slits and the screen is 2.0 m. If the wavelength of light used is 5.89x10-7m, determine the slits separation.
Using a 685 nm wavelength laser, you form the diffraction pattern of a 1.01 mm wide slit on a screen. You measure on the screen that the 15th dark fringe is 9.23 cm away from the center of the central maximum. How far is the screen located from the slit?
Using a 697 nm wavelength laser, you form the diffraction pattern of a 1.11 mm wide slit on a screen. You measure on the screen that the 11th dark fringe is 8.33 cm away from the center of the central maximum. How far is the screen located from the slit?
