Question

Two point sources produce waves of the same wavelength that are in phase. At a point midway between the sources, you would expect to observea) constructive or destructive interference depending on the wavelength.b) destructive interferencec) no interferenced) constructive interferencee) alternating constructive and destructive interference interference

Answer 1

Answer:

Constructive Interference.

Explanation:

Constructive Interference.

Definition:

Two waves meet in such a way their highs(Crests) combine to form a new waves whose magnitude is the sum of magnitude of combining waves.

Since two waves have same wavelength and are in phase so when they combine they well form a way which has the magnitude equal to the sum of the magnitude of both waves.

Reasons why it is Constructive Interference:Waves

• Have Same wavelength
• Are in phase (Can have phase difference of 2π
• Have crests aligned with each other (Appear at same point)
