How does the zoom on binoculars work?

I know light travels in straight lines but how do you draw things into focus, and when it gets all blurry whats actually happening? Am I seeing stretched out wavelengths of light or what?

But what happens to the particles of light as it passes through the lens? Why can you focus on something far away and something close is completely blurry and out of focus? Is the particle actually being spread out and "smeared"? Because if theyre just points of weightless matter that doesnt make sense. You think you would just see more detail.

Well my field is chemistry, not physics. I do remember a bit from optics though. Light will slow while passing through a solid like a lens, then leave the lens at the speed of light (think of a traffic jam). How much so depends on its refractive index. Why things appear in focus and blurry at different lengths depends on the focal length of the lens. It works the same with your eye. If you look at something in the distance or up close, things at another distance will appear out of focus. Your binoculars have these lenses. By turning them, youre adjusting the distance they are from your eyes, thus adjusting the focal point.

So its essentially adjusting the aiming point of the focal convergence?
That would mean when its blurry you're just catching the edge's of the light. A partial impression, if you will. Because you're not really looking at it, you're just catching the ripples of its intersection with the center of focus. Which makes it blurry.
EDIT: Which touches on its wave-particle duality. Something beyond explanation.

Yeah, pretty much. Its really a function of geometry. Light leaves the lens at an angle which depends on where it entered the lens (also how concave/convex the lens is). Blurry images are just outside of the center of convergence.

Well kinda. The wave-particle duality is actually very well understood. Google the photoelectric effect. Optics arent really a function of wave-particle interaction. It deals more with geometry and reflection/refraction.

Scratch that, Im thinking of something else. Wave/particle duality experiments are a function of optics, but not in the case of lenses. Its still geometry kinda stuff.

Ok I think I get it. If you place your focus here----X when the only objects are farther away like this ------------X only a limited number of those photons are actually being captured right?
EDIT: Theres two points of convergence. The eye and the object. The lens acts as an interface for the light and bends it into convergence for the observer.
So something wide like this | | | |
Is bent into a single point like this .
Which is our perception of it.

Ya. The eye also acts as a lens. Its not that youre missing out on photons, its just that they arent converging in your eye equally.

You say equality but Im kind of puzzled by this terminology. Is there a band per photon that I need to find the center of?

No but there is a point of focus for each object at different distances from the lens.

Well...kinda. Not a "band" in the sense of wavelength or anything in this case. More like trajectory and angle of refraction along with distance from the lens. Photons are passing through the lens from everything in your field of vision. Everything at every distance. The photons that hit your "sweet spot" in the eye are controlled by the lens which you can adjust. Photons from everything else are still passing through the lens, but because they are at a different distance they dont hit your sweet spot.

Its bascially like how a magnifying glass works: when u focus the light to a small spot, it glows hot and can burn leaves because it focuses a large area of light into a small area on the ground.
Same as binoculars and your eyes.

Thats not really an accurate description of whats happening though, whats being focused for one, and how does this occur for another. I find humans all to commonly drop the matter once they feel they've clothed it in language, yet all too often true understanding eludes the people that drop this "knowledge"

Its such a deceptively simple thing, and people try to brush it off as angles and geometry, but the true reality is much more complex than that. I dont even feel I understand it yet. Theres a dimension in there that I cant quite comprehend.

Like if you cant describe it in language thats readily apparent to everyone I dont think you understand it. thats my idea anyways. Even einstein's theory of relativity is readily comprehensible. Speed has a direct correlation to the experience of time. That opens up a whole plethora of phenomena that we werent aware of beforehand, and its easily explainable. This on the otherhand, not so much.

"You can probably see where we're heading. If you want to see something in the distance, you can use two convex lenses, placed one in front of the other. The first lens catches light rays from the distant object and makes a focused image a short distance behind the lens. This lens is called the objective, because it's nearest to the object you're looking at. The second lens picks up that image and magnifies it, just like a magnifying glass magnifies an image on paper. If you put the two lenses in a closed tube, hey presto, you have a telescope."
From here: http://www.explainthatstuff.com/binoculars.html
I learned something today: binoculars are basically two compact telescopes and there are two mirrors on each side that focus via the focus wheel mechanism, thats why it looks like it "zooms" when u focus the light. Convergence then divergence with zooming (aka moving the mirrors back and forth).

Thats literally all there is to it. Its angles and geometry.

Binoculars and cameras depend on the wavelike properties of light to focus an image onto a surface - binoculars on the retina and cameras on the film or sensor. Digital camera sensors actually take advantage of light's quantum properties by counting individual photons.
Lenses do two things. They collect light and they focus it, and there is a trade off between the two. A very large lens can collect a lot of light, but only focus on things at a specific distance. A small lens doesn't collect as much light but has much more in focus.
A pinhole lens will have everything in focus. Someone who normally requires glasses to focus things at a distance can look trough a hole In paper or through their fingers and focus on distant objects without glasses

I study physics. The branch of optics you guys are interested in is called geometric optics. If you're genuinely interested in learning about geometric optics, here's a good basic introduction. It uses a bit of mathematics like trigonometry and simple algebra, so it's highschool-level or possibly first-year undergrad if somebody had no background. The relevant part is III, "Image formation with lenses", but you'll have to read everything up until that point to really understand it.
