Question

Two sources of waves are in phase and produce identical waves. These sources are mounted at the corners of a square and broadcast waves uniformly in all directions. At the center of the square, the waves will always produce constructive interference no matter which two corners of the square are occupied by the sources?

Answer 1

Pure constructive interference occurs when two identical waves arrive at the same point exactly in phase. This phenomenon can be observed at the center of the square, regardless of which two corners the sources are located at.

Step-by-step explanation:

Pure constructive interference occurs when two identical waves arrive at the same point exactly in phase. When waves are exactly in phase, the crests of the two waves are precisely aligned, as are the troughs. This superposition produces a wave that has twice the amplitude of the individual waves but has the same wavelength. This phenomenon can be observed at the center of the square, regardless of which two corners the sources are located at.
