Question

In Young's double slit experiment with slit separation $d$, a monochromatic light of wavelength $\lambda$ is used. The angular separation of the fringes is\

Professor PC Thomas Classes · Answer

B)Fringe width, $\beta=\frac{\lambda D}{d}$ Angular separation of the fringes is\ $	heta=\frac{\beta}{\mathrm{D}}=\frac{\lambda \mathrm{D}}{\mathrm{dD}}=\frac{\lambda}{\mathrm{d}}$\
