Identify the correct statement related to angular fringe width $\delta$.

Question

Professor PC Thomas Classes · Answer

The angular fringe width $\delta$ is defined as $\delta=\frac{(1)}{D}=\frac{\lambda}{d}$ \Note that - \it depends on $\mu$ because $\mu=\frac{\lambda_{	ext {air }}}{\mu}$ - it is independent of $n$. - it is independent of $D$.
