Vedclass · Answer

(D) The width of the diffraction bands in a single-slit diffraction pattern is given by the formula $\beta = \frac{2\lambda D}{a}$,where $\lambda$ is the wavelength of the light,$D$ is the distance of the screen from the slit,and $a$ is the width of the slit.Since the wavelength of blue light $(\lambda_{blue})$ is smaller than the wavelength of red light $(\lambda_{red})$,the width of the diffraction bands $\beta$ will decrease.Therefore,when red light is replaced by blue light,the diffraction bands become narrower and more crowded together.

$A$ diffraction pattern is obtained by using a beam of red light. What will happen if the red light is replaced by blue light?
