Question

prove that in diffraction from a slit the secondary maximum and minima are of the same width​

Answer 1

Answer:

A single slit produces an interference pattern characterized by a broad central maximum with narrower and dimmer maxima to the sides.

There is destructive interference for a single slit when D sin θ = mλ, (form = 1,–1,2,–2,3, . . .), where D is the slit width, λ is the light’s wavelength, θ is the angle relative to the original direction of the light, and m is the order of the minimum. Note that there is no m = 0 minimum.
