Question

Consider the diffraction pattern obtained from the sunlight incident on a pinhole of diameter 0 . 1 μ m . If the diameter of the pinhole is slightly increased, it will affect the diffraction pattern such that, its size increases, and intensity increases, its size decreases, and intensity decreases, its size decreases, but intensity increases, its size increases, but intensity decreases

MARKS App · Accepted Answer

sin θ = m λ a when a increases, θ decreases, width decreases width decreases so intensity will increases
