Vedclass · Answer

(B) The angular width of the central maximum in a single slit diffraction pattern is given by $	heta = \frac{2\lambda}{a}$, where $\lambda$ is the wavelength of light and $a$ is the slit width.Since the wavelength of blue light $(\lambda_{blue})$ is smaller than the wavelength of red light $(\lambda_{red})$, the angular width of the diffraction fringes decreases.Therefore, the fringes become narrower and more crowded together.

$A$ single slit diffraction pattern is obtained using a beam of red light. If the red light is replaced by blue light, then:
