Question

In a Young's double slit experiment, light of 500 nm is used to produce and interference pattern. When the distance between the slits is 0 . 05 mm , the angular width (in degree) of the fringes formed on the distance screen is close to :, 0 . 17 °, 0 . 57 °, 1 . 7 °, 0 . 07 °

MARKS App · Accepted Answer

β 0 = λ d = 500 × 10 − 9 5 × 10 − 5 = 10 − 2 rad ∴ β 0 = 0 .57 °
