Vedclass · Answer

(C) The relationship between phase difference $(\Delta \phi)$ and path difference $(\Delta x)$ is given by: $\Delta \phi = \frac{2\pi}{\lambda} \Delta x$ For constructive interference,the phase difference must be an even multiple of $\pi$: $\Delta \phi = 2n\pi$,where $n = 0, 1, 2, 3, \dots$ Equating the two expressions: $2n\pi = \frac{2\pi}{\lambda} \Delta x$ Solving for path difference $(\Delta x)$: $\Delta x = n\lambda$

For the constructive interference,the path difference between the two interfering waves must be equal to:
