Vedclass · Answer

(B) In the phenomenon of interference,destructive interference occurs when the waves arrive at a point out of phase. The condition for destructive interference is that the path difference between the two waves must be an odd multiple of half the wavelength. Mathematically,this is expressed as $\Delta x = (2n + 1)\frac{\lambda}{2}$,where $n = 0, 1, 2, 3, \dots$ and $\lambda$ is the wavelength of the light used.
