Quizplus · Accepted Answer

When two sources emit waves of different frequencies that do not remain in phase, the interference pattern they produce will vary both spatially and temporally, leading to fringes that appear to move in space and change over time. This is because the phase relationship between the waves changes continuously, altering the interference pattern.
