#refraction

(Beer) Glass 🍺 for #fotovorschlag "Objekte, die mit "G" beginnen oder so aussehen" / "Objects beginning with "G" or looking like it"

I'm not doing too great again, (it's grand honestly, just ✨chronic illness✨ stuff), and I'm running out of "good" photos so you're going to be getting the bad photos or reposts as I've run out of material. 😂
However, if anyone has any ideas of fun photos that you can do at home (with not too much extertion) I would be really grateful! Thank you! 🫂♥️✨

The photo is of a distorted reflection of a street scene with a person on a bike, as seen through a glass of beer.
The reflection has a grand, yellow building facade with a colonnade. On the street, blurred figures (it's just one person reflected a few times) on a bike are visible.The reflections are warped and fragmented due to the curvature and thickness of the glass.

GN fam! A calving glacier made of safety glass on a window pane in an open container at night #WinterVibes Fascinating #physics: #reflections, #refraction #ALText: #strongerTogether, #inclusion:) #abstractArt #minimalism #EastCoastKin #PhotographyIsArt #JanuArty2026 #ArtYear #PhotographersofBluesky

Three characteristically shaped shards have broken off from a large piece of safety glass. The safety glass rests on dew-covered window glass, which reflects the night sky. The container holding the glass waste is illuminated by white LED light. The safety glass vaguely resembles ice, the individual shards icebergs, and the droplet-covered black glass plate a body of water.

Yep there is, @soph0517.bsky.social‬ and thank you for sharing this great take! Faszinating #physics: #reflections, #refraction and surface tension of the #rainDrops #AlphabetChallenge #WeekAforAbstract #EastCoastKin #macro #MacroPhotography

Several raindrops lie on the back of a green oak leaf lying on the ground. They reflect their surroundings, a forest path, and act like magnifying glasses.

@indigosan.bsky.social‬ shared a stunning capture and used #ALText, because #inclusion is #fairness: Thank you so much! Playing with frozen stuff in front of my house :) #MacroPhotography #abstractArt #PhotographyIsArt Fascinating #physics: point #reflection and #refraction

I illuminated a block of ice at night with blue light and placed a small glass sphere (diameter about 3 cm) in front of it, which created a point reflection.

A round piece of ice, resting on top of a black shard of glass, is illuminated from the side by the sun. Countless tiny bubbles rise very slowly within the ice, leaving traces of their movement. The bubbles reflect the shard and the light. Some bubbles shimmer with spectral colours due to refraction. A tiny, light green piece of moss, frozen to the lower part of the piece of ice, and its reflection can be seen on the left of the image. The ice piece is reflected, partially distorted, in the black glass that is covered with a thin film of ice and water. A narrow ridge at the edge of the ice reflects the blue of the sky.

zu saitenweise hab ich nichts, dann nehm' ich eben was mit tröpfchen, das bild ist von gestern

nahaufnahme, makro. unter einem mit grobem fasermaterial, sisal oder so, umwickelten teil stehen einzelne dieser fasern etwas ab und an denen haben sich wassertröpfchen gebildet oder gesammelt. sie leuchten im diffusen gegenlicht eines bewölkten himmels, in ihnen spiegelt sich kopfstehend die welt, die hier aus beige-grüner wiese und grellhellgrauem himmel besteht. nur der vorderste und zugleich unterste und größte der wassertropfen ist ganz scharf abgebildet, die anderen zunehmend unscharf. der hintergrund aus dem beige-grün der wiese ist sehr unscharf, wolkig, struktur nur noch zu erahnen.

Atmospheric refraction, due to the different temperature/altitude profile in the atmosphere at different times of day...makes distant mountains appear taller or shorter.

The attached photo is a comparison of what I shot yesterday afternoon and this morning. The camera was set up within inches of the same location for both shots, and those mountains are between 50 and 120 miles away...so I'm saying that any parallax effect from camera location is essentially zero.

I have annotated with arrows where it's easy to make a comparison of how the near and far ridge lines overlap differently in the two photos.

This is a follow up to:

Imagine the care that was needed to conduct surveys before the GPS/GNSS era:
explorersweb.com/the-five-men-

"The Great Theodolite built by Troughton & Simms in London stood nearly 1.5m high, had a horizontal circle one meter in diameter, and could read angles to a single second of arc. Moving it required 30 porters and sometimes elephants."

"The reduction of Nicolson’s observations was a colossal task. Each ray from each station had to be corrected for instrumental error, for temperature and pressure, and for the curvature of the Earth. Above all, they needed to correct for atmospheric refraction, which at those distances could amount to six or seven minutes of arc and change from hour to hour."

Hi fam, have a fulfilling day! Low Budget #Photography Fascinating #physics: #reflections, point reflection and #refraction by #drops and #droplets #WinterVibes #MacroPhotography #abstractArt #PhotographyIsArt I used #ALText that makes text audible to describe the picture: #inclusion is #fairness :)

Countless condensation droplets on a window reflect a snow-covered garden with large trees, a field, a forest edge, a blue sky, and the sun. The drops at the top of the image also reflect part of the brown windowsill. I rotated the image 180 degrees because point reflection occurs within the drops, and the reflections are upside down.

There is currently a halo (22° halo, en.wikipedia.org/wiki/22%C2%B0) around the moon.

The ring is created by moonlight refracted by hexagonal, non-oriented ice crystals. These ice prisms are found in high-altitude clouds (cirrus clouds). This type of halo is quite common. Its radius is 22°, which is about 44 full moon diameters.

More #refraction in the hallway at 10:30 in the morning when me and my youngest were about to leave the house for a scouts event. We loved the tiny #rainbow #dispersion

A lovely ray of light in the halway. #refraction #dispersion

A thin ray of diffracted light, a tiny rainbow, across the floor on the hallway. On the floor there are strewn objects: a black tshirt in a heap, a reflex triangle, shoes, te bus balls, a clarinet case, a piece of paper folded up, a large tote. The floor is light brown.

Our moon, winner: The Trace of Refraction by Marcella Giulia Pace

This image from Sicily in Italy captures the phenomenon of atmospheric , where moonlight passes through dense layers of Earth’s atmosphere near the horizon, bending in a manner similar to light rays through a prism.



The redness of the moon can be explained by a process known as Rayleigh scattering: smaller particles in the atmosphere scatter shorter wavelengths of light, resulting in longer wavelengths, namely red, being more predominant
