Light shines through a single slit whose width is 5.6 × 10-4 m. a diffraction pattern is formed on a flat screen located 4.0 m away. the distance between the middle of the central bright fringe and the first dark fringe is 3.3 mm. what is the wavelength of the light?

462 nm

Explanation:

Given: width of the slit, d = 5.6 × 10⁻⁴ m

Distance of the screen, D = 4.0 m

Fringe width, β = 3.3 mm = 3.3 × 10⁻³ m

First dark fringe means n =1

Wavelength of the light, λ = ?
