Determine the angular separation between consecutive bright fringes for a Young's double slit experiment using blue-green light of wavelength 500 nm . The distance between the slits is 2.0 10⁻³ m .

Step-by-step solution

The angular separation between consecutive bright fringes is given by = d Given = 500 nm = 5 10⁻⁷ m and d = 2.0 10⁻³ m = 5 10⁻⁷ 2.0 10⁻³ = 2.5 10⁻⁴ rad Converting radians to degrees: = 2.5 10⁻⁴ 180^ 0.014^
