Optical physics is subfield of atomic, molecular, and optical physics. It differs from general optics in that it is primarily concerned with the study of optical fields and their interactions with matter in the microscopic realm. Atomic, molecular, and optical physics is the study of matter-matter and light-matter interactions on the scale of single atoms or structures containing a few atoms. ... Related topic: List of optical topics Optics (appearance or look in ancient Greek) is a branch of physics that describes the behavior and properties of light and the interaction of light with matter. ... Interaction is a kind of action which occurs as two or more objects have an effect upon one another. ... Matter is commonly referred to as the substance of which physical objects are composed. ... A microscope (Greek: micron = small and scopos = aim) is an instrument for viewing objects that are too small to be seen by the naked or unaided eye. ...
In physics, physicaloptics, or wave optics, is the branch of optics which studies interference, diffraction, polarization, and other phenomena for which the ray approximation of geometric optics is not valid.
Physicaloptics is also the name of a high frequency approximation (short-wavelength approximation) commonly used in optics, electrical engineering and applied physics.
The ray optics field or current is generally not accurate near edges or shadow boundaries, unless supplemented by diffraction and creeping wave calculations.
Optics (ὀπτική appearance or look in ancient Greek) is a branch of physics that describes the behavior and properties of light and the interaction of light with matter.
The field of optics usually describes the behavior of visible, infrared, and ultraviolet light; however because light is an electromagnetic wave, analogous phenomena occur in X-rays, microwaves, radio waves, and other forms of electromagnetic radiation.
Physicaloptics models the propagation of complex wavefronts through optical systems, including both the amplitude and the phase of the wave.
