13th International Conference on Optics, Photonics & Laser

EURO-OPTICS 2020   1 3 th  International Conference on Optics, Photonics & Lasers    April 22-23, 2020 Berlin, Germany . Please see: https://optics.physicsmeeting.com/ Sessions/Tracks Track 1:  Classical & Physical Optics Classical optics is divided into two main branches: geometrical (or ray) optics and physical (or wave) optics. In  geometrical optics , light is considered to travel in straight lines, while in physical optics, light is considered as an electromagnetic wave.  Physical optics   is the study of the wave properties of light, which may be roughly grouped into three categories: interference, diffraction, and polarization And In  Physical optics,  light is considered to propagate as a wave. This model predicts phenomena such as interference and diffraction which are not explained by  geometric optics . The speed of light waves in air is approximately 3.0×108 m/s (exactly 299,792,458 m/s in va...
