Vedclass · Answer

(B) The width of the central maximum in a single-slit diffraction pattern is given by the formula $\beta = \frac{2\lambda D}{a}$,where $\lambda$ is the wavelength of light,$D$ is the distance of the screen from the slit,and $a$ is the slit width.Since the wavelength of green light $(\lambda_{green})$ is smaller than the wavelength of red light $(\lambda_{red})$,the width of the diffraction pattern $\beta$ is directly proportional to the wavelength $(\beta \propto \lambda)$.Therefore,when green light is used,the diffraction pattern will shrink or become closer together.
