Question

What is the condition for the two waves to interference constructively and destructively:

(a) in terms of path difference.

(b) in terms of the phase difference.

Solution

The condition for the two waves for constructive interference and destructive interference are:
(a)
$straight x equals nλ space space left square bracket constructive space interference right square bracket space space equals fraction numerator 2 straight n minus 1 over denominator 2 end fraction straight lambda space space left square bracket destructive space interference right square bracket$
(b) $straight ϕ equals 2 nπ$ (constructive interference)
$space equals left parenthesis 2 straight n minus 1 right parenthesis straight pi$ (destructive interference)
