Constructive interference

Vedclass · Answer

(A) The condition for interference depends on the path difference $(\Delta x)$ and the wavelength $(\lambda)$.Constructive interference occurs when the path difference is an integer multiple of the wavelength,i.e.,$\Delta x = n\lambda$,where $n = 0, 1, 2, 3, \dots$.Rearranging this,we get $\frac{\Delta x}{\lambda} = n$.Since the problem states that the ratio of path difference to wavelength is an integer,it satisfies the condition for constructive interference.Therefore,constructive interference is formed.

If $\frac{\text{Path difference}}{\text{Wave length}} = n$ (where $n$ is an integer),what kind of interference is formed?
