In a double-slit experiment, coherent light of wavelength 610 nm is incident upon two slits that are separated by 0.266 mm. The fringe pattern is viewed on a screen that is 1.34 m away. What is the width of the central maximum on the screen? Give your answer in cm.

Problem 7:   Consider light falling on a single slit, of width 1.05 μm, that produces its first minimum at an angle of 33.6°.Randomized Variables θ = 33.6°w = 1.05 μm   Calculate the wavelength of the light in nanometers.

A technician is performing Young's double-slit experiment for his supervisor. He directs a beam of single-wavelength light to a pair of parallel slits, which are separated by 0.132 mm from each other. The portion of this light that passes through the slits goes on to form an interference pattern upon a screen, which is 4.50 meters distant.The light is characterized by a wavelength of 590 nm. (a)What is the optical path-length difference (in µm) that corresponds to the fifth-order bright fringe on the screen? (This is the fifth fringe, not counting the central bright band, that one encounters moving from the center out to one side.) ?µm (b)What path-length difference (in µm) corresponds to the fifth dark fringe that one encounters when moving out to one side of the central bright fringe? ?µm

Fringes in the Thomas Young experiment are produced using sodium light of wavelength 613 nm and two slits which are 1.1 mm apart. If the fringes are formed on a screen 0.9 m away from the slits, how far is the third order bright fringe from the middle of the screen? Give your answer in millimeters (mm).
