a) Two thin slits separated by 0.0822 mm are illuminated with light from a He-Ne laser (λ = 633 nm), producing interference fringes on a distant screen. Discover the angle between the centers of the next bright fringe and the central bright fringe.
b) Blue interference fringes are formed on a screen 2.3 m away from a double slit illuminated with monochromatic light of wavelength 484 nm. The distance among the centers of adjacent fringes is 3.6 mm. Discover the separations between the two slits.
c) How far is the second dark fringe to the right of the central bright fringe in the double-slit interference pattern seen on a screen 4 m from the slits? The slits are separated by 0.4 mm and are illuminated with monochromatic light of wavelength 619 nm.
