If D = 2m, d = 1mm (1 × 10⁻³ m), and λ = 600nm (600 × 10⁻⁹ m), determine the total width of the central bright fringe (2β).

Question

Accepted Answer

2β = 2mm. The width of the central bright fringe is given by 2β = 2λD/d. Substituting the values: 2 × (600 × 10⁻⁹) × 2 / (1 × 10⁻³) = 2 × 10⁻³ m = 2 mm.

If D = 2m, d = 1mm (1 × 10⁻³ m), and λ = 600nm (600 × 10⁻⁹ m), determine the total width of the central bright fringe (2β).
