optics
Optics is the branch of physics which involves the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.
Most optical phenomena can be accounted for using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be accounted for in geometric optics. Historically, the ray-based model of light was developed first, followed by the wave model of light. Progress in electromagnetic theory in the 19th century led to the discovery that light waves were in fact electromagnetic radiation.
Some phenomena depend on the fact that light has both wave-like and particle-like properties. Explanation of these effects requires quantum mechanics. When considering light's particle-like properties, the light is modelled as a collection of particles called "photons". Quantum optics deals with the application of quantum mechanics to optical systems.
Optical science is relevant to and studied in many related disciplines including astronomy, various engineering fields, photography, and medicine (particularly ophthalmology and optometry). Practical applications of optics are found in a variety of technologies and everyday objects, including mirrors, lenses, telescopes, microscopes, lasers, and fibre optics.

Hello everyone, I am selling my gently used Trijicon Credo 1-6x24 FFP with the Red MRAD Segmented Circle reticle LPVO. Going in a different direction with the build but it’s a fantastic 1-6 very clear glass, in very good condition. Comes with everything it shipped with. I don’t think you can get...
Sup, ya'll please bear with me as this post might seem a bit pedantic but I'd really appreciate your feedback as always. As the internet seems to careen back, forth and sideways from one knee jerk reaction to another in the "tactical trends" of the gun world, do any of ya'll still prefer...
Unfortunately parting ways with this. Not looking for trades at the moment. Preferred local pickup. A couple of small scratches on the rear lense cover and on the battery cap. This has been to the range no more than 3 times, original box, tool, paperwork etc. Glass is clear as day and dot is...
Hey ya’ll. I’m selling my Holosun 507c, in very good condition including the original box and included things. Still in like new condition, mounted on a pistol but not fired. No damage of any kind. Recently purchased from Oregon Rifleworks. Will upload some pics as soon as I get home.

here I have a very lightly used acog. Clean glass, piggy back rmr plate. Currently have no use for it so figured I’d let someone else enjoy it. It is rattle canned but I can strip the paint off if need be. Not really after trades, but if you have something interesting in my favor shoot your...

I’ve got everything I want not interested in a 50cal.
The only item I haven’t shot is a 6.5.
I don’t have the opportunity to shoot more than 300 yards. I’ve overspent on optics. I want a mil dot.
Leopold makes a vx5
Is $1000 worth it?
I like smaller caliber in the winter...
Selling for relatively cheap because one of the threads popped out when I was tightening down on the mount. Strapped for cash right now and in the process of moving. 1.57 scalarworks LEAP mount included, if you do choose to snag this, I would advise that the mount does not get removed from the...
