Theory and background
What is wave optics?
Wave optics explains light behavior using wave principles. Interference occurs when waves combine, while diffraction describes spreading around openings or edges.

Frequently asked questions
Wave Optics FAQ
01
What is interference?
Interference happens when waves overlap and combine to create brighter or darker regions.
02
What is diffraction?
Diffraction is the spreading of waves when they pass through a narrow opening or around an obstacle.
03
How does wavelength affect fringes?
Longer wavelengths generally produce wider fringe spacing in an interference pattern.
04
Why does intensity vary?
Intensity changes because waves add constructively in some places and destructively in others.
