- A laser emitting light with a wavelength of 560 nm is directed at a single slit, producing an interference pattern on a screen that is 3.0 m away. The central maximum is 5.0 cm wide. a. Determine the width of the slit and the distance between adjacent maxima. b. What would the effect on this pattern be, if the width of the slit was smaller? the screen was moved further away? a larger wavelength of light was used? c. How would this interference pattern differ if the light was shone through a 1. double slit? 2. diffraction grating?Light of wavelength 674 nm is incident on a narrow slit. The angle between the first diffraction minimum on one side of the central maximum and the first minimum on the other side is 1.31°. What is the width of the slit? Number i UnitsA laser beam (λ=497 nm) is put through a beam splitter to give 2 equal intensity beams traveling parallel to one another. One of these beams is directed through a double slit apparatus, and the other beam through a single slit apparatus. The single slit and the double slits are in the same plane and both display fringe patterns on a screen a distance L= 3.3 m away. a. The slit spacing of the double slit apparatus is 0.63 mm. What is the distance from the center of the double slit fringe pattern to the 5th dark fringe? b. If the third dark fringe of the single slit pattern is the same distance from the center of the single slit pattern as the result for part (a), what is the single slit width? To continue, please enter the result of part b) in mm. Round your answer to 2 decimal places
