Question

pling leaming Dwo sets of parallel waves, with the same wavelength but different initial phases, are directed at a barrier. Each wave is incident on a single tiny hole in the barrier, as shown in the diagram, where you can assume the lines represent the peaks of the waves. The two holes therefore act as sources of spherical waves, which spread out and interfere with each other Determine what kind of interference occurs at each labeled point, and sort the points by whether they correspond to regions of completely constructive interference, completely destructive nterference, or n-between Constructive Destructive interference interference In-between ADE BC F Map

Explanation / Answer

At constructive ineterference displacement of two waves is maximum (waves are in phase)

At constructive ineterference displacement of two waves is minimum (waves are out of phase)
Costructive interferece : A , D, B

Destructive interference = c, F

In between = E
