Part 1
Young's experiment is performed with light from
excited helium atoms λ = 550 nm. Fringes are
measured carefully on a screen 1.6 m away from
the double slit, and the center of the 15th bright
fringe is found to be 8 mm from the center of the
central bright fringe and at an angle above the
central axis.
