In 1873, the German physicist Ernst Abbe realized that the resolution of optical imaging instruments, including telescopes and microscopes, is fundamentally limited by the diffraction of light.

Young's experiment showed interference of light. As only waves demonstrate interference, this confirmed that light was a wave motion not a stream of particles. Watch this video for a practical ...

Optical physics is the study of the fundamental properties of light and its interaction ... refraction, diffraction and interference, and also studying the quantum mechanical properties of ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...
