- The interference figure of a set of double slits is measured at a stop. The experiment is performed with a laser with a wavelength of 450nm (approach the speed of light to 300,000 km/s in this situation) and it is measured that the interference maximum m=2 is 10mm away from the main maximum.Then, 2 pieces of glass are placed in front of each of the slits. The piece of glass P1 causes a delay in the wave (in relation to a wave that propagates in the air) of 7.5x10^(-16)sThe piece of P2 glass causes a delay of 3.75x10^(-16)s.

What is the separation of the two slits?A hydrogen gas discharge lamp is used as a coherent light source illuminating NN slits in a barrier with a slit separation of 28 μmμm. The interference pattern is projected on a screen 2.00 m from the barrier. The first-order principal maxima to one side of the central maximum. The number of slits is sufficiently large that the individual lines are sharp and widely separated. Note that there are four different colors appearing in the source, violet is the color closest to the central maximum. λ=656λ=656 nm (red) λ=486λ=486 nm (cyan) λ=434λ=434 nm (blue-violet) λ=410λ=410 nm (violet) The blue-violet line is thin and somewhat faint, and it may be difficult to see without enlarging the figure. When viewing multiple orders of the interference pattern, the color sequence may change due to the interleaving of the different orders. 1.
