Question

There is a destructive interference between the two waves of wavelength λ coming from two different paths at a point. To get maximum sound or constructive interference at that point, the path of one wave is to be increased by-

TestHub · Accepted Answer

For destructive interference, the path difference is $(n + \frac{1}{2}) λ$ . To achieve constructive interference, the path difference must be $nλ$ . Increasing the path by $\frac{λ}{2}$ changes the path difference from $(n + \frac{1}{2}) λ$ to $(n + 1) λ$ , resulting in constructive interference.

The final answer is $\frac{λ}{2}$ .
