Two lasers are shining on a double slit, with slit separation d. Laser 1 has a wavelength of d/20, whereas laser 2 has a wavelength of d/15. The lasers produce separate interference patterns on a screen a distance of 4.30 m away from the slits. A. What is the distance between the first maxima (on the same side of the central maximum) of the two patterns? B. What is the distance between the second maximum of laser 1 and the third minimum of laser 2, on the same side of the central maximum?

A 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

A Young's interference experiment is performed with blue-green laser light. The separation between the slits is 0.500 mm, and the screen is located 3.26 m from the slits. The first bright fringe is located 3.32 mm from the center of the interference pattern. What is the wavelength of the laser light?  nm

A beam from a krypton ion laser (gamma = 461.9 nm) falls on a single slit, producing a central maximum 4.0cm wide on a screen 1.50m away. a. Calculate the slit width b. Determine the angle between the rays travelling to the 2nd minima and the rays travelling to the central maxima.
