PhysicsEasysingle choice

A parallel beam of monochromatic light falls normally on a single narrow slit. The angular width of the central maximum in the resulting diffraction pattern

Options:

Answer:

Solution:

Width of central maximum $W_{c} = 2 ⌊ \frac{λ D}{a} ⌋$ $\Rightarrow W_{e} \propto \frac{1}{a}$ $∴$ Angular width of principal maximum decreases with increase in width of the slit.
