Diffraction is the bending of waves around obstacles and through openings. It demonstrates that light and other waves don't travel in perfectly straight lines.

Ofte stilte spørsmål
Why does diffraction matter in optics?
Diffraction limits the resolution of microscopes, telescopes, and cameras. Narrower slits and shorter wavelengths improve resolution.
How does diffraction differ from interference?
Diffraction is light bending around obstacles, while interference is patterns from overlapping waves.
