What is the superposition principle in interference of light?
Understand the Problem
The question is discussing the superposition principle in the context of wave interference. It covers constructive and destructive superposition of waves and how they affect the resultant displacement and intensity.
Answer
The superposition principle involves adding wave displacements at overlapping points.
The superposition principle states that when two or more waves overlap, the resultant displacement at any point is the sum of the displacements of the individual waves. In constructive interference, amplitudes add; in destructive interference, they subtract.

More Information
Superposition is key in phenomena like interference, where light waves can constructively or destructively combine to enhance or diminish intensities.
Tips
A common mistake is not considering the direction (phase) of wave displacements when adding them.
