Consider a plane inclined at an angle
45∘ with the horizontal has two slits (
S1andS2 separated by a distance d =
√2 mm The screen is placed at a distance of D = 10 m A parallel monochromatic light beam of wavelength 5000
∘A is incident on the slits as shown If the fringe width of interference pattern on the screen is
k×10−3 meter then find the value of k
