Question

For a parallel beam of monochromatic light of wavelength &#955; , diffraction is produced by a single slit whose width a is of the order of the wavelength of the light. If D is the distance of the screen from the slit, the width of the central maxima will be:

Quantrex Academy · Accepted Answer

Correct answer: A. 2 D λ a

Linear width of central maximum. D 2 θ = 2 D θ = 2 D λ a
