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.
so whats the deal with vortex optics? i know they have a stellar warranty and seem to be well made, but why is it the most common scope being sold on here? are people not happy with them or what?

I have for sale a custom rifle i had built last year. it is a base Remington 30-06 long action mounted with a tim 12oz trigger with safety with a PAC-NOR barrel of 1.25" diam, they matched the bolt face and action with the chamber and had a large recoil lug installed and the...
Nothing new here, but still wanted to share a fun project with some pointers (no pun intended). Originally I was going to mount a fastfire 3, but came across this vortex viper reflex sight. It's a really nice unit, and it's square, so the milling was going to be a bit simpler.
I found a slide...

So I'm thinking about getting one of base plates that replaces the rear sight on my glock just to try out before I purchase a mos glock.has anybody uses one and was prettt happy with the results and what red dot did you use.im looking for a inexpensive one that will hold up for a bit before I...
DESCRIPTION:
This has been gently used from a bench only and lovingly cared for. Glass is perfect and no blemishes that my eyes can detect. It comes with the original box, manual, and tools for zeroing. I'm throwing in the sunshade and a Badger Ordnance mount. The scope is awesome but I have...
I'm looking for a Schmidt and Bender or Kahles with the MSR reticle in a 5-25 or 6-24 (I'd not say no to one of the 3-27)models though something around there is fine mag wise. Absolutely nothing wrong with this scope but I just picked up a 338 and would like some more mag. As for the additional...
Was wondering what most people do with their optics batteries when not in use for a month or more. Cheap Chinese batteries should come out, but what about name brand like Duracell or Eveready? Still a concern of leakage and damaging the electronics?
New to the world of AR-15's. I have Mag pul iron flip ups, but looking for something I can reach out to 100 to 200 yards with on the cheaper end. I'm not going to be shooting past 200 any time soon so I can't justify throwing my Weaver on there. Any suggestions? :s0107:
