Optics is a branch of physics describing the behaviors and properties of light (electromagnetic waves). Questions regarding the properties of light, it's interactions with matter and the instruments used to detect and deflect (or concentrate) light should be posted here.

Some Relevant Categories:

  • geometric optics (ray theory)
  • physical optics (diffraction & interference)
  • Quantum optics (photonic behavior)

Lenses and mirrors would apply.
