Whether the diffraction effects from a slit will be more clearly visible or less clearly if the slit width is increased? |
|
Answer» Since most of the diffracted light is distributed between an angle θ such that sinθ = -λ/b to sinθ = λ/b, where b is the slit width. As b is increased, θ decreases. It means the cone of divergence narrows down and the diffraction effects will be less clearly visible. |
