When light inside water hits the surface at a steep enough angle, it stops escaping and reflects completely back into the water. It’s called total internal reflection, and it’s a reminder that even light doesn’t always travel the path we expect.

The law of reflection states that the angle of incidence always equals the angle of reflection: when light hits a surface, it bounces off at the same angle it arrived, measured from an imaginary line perpendicular to the surface (the normal).

Every year, in the middle of February, the sunlight falls on this waterfall called «Horsetail,» and because of the specific angle at which the light hits, it looks like the water is on fire. The water starts to glow orange and red.

“When that light hits the sky, it’s not just a call. It’s a warning… To them.”

🌎 Very intriguing!! There is a planet larger than earth, made up entirely of water. It’s called TOI-1452b and it’s 100 light years away from earth. It is a true WATER WORLD.

A laser beam can travel along a falling stream of water, trapped by total internal reflection, the same principle used in fiber optic cables.

$The patterns of light on the sea floor. They are called caustics: they are created by light refracted and reflected from the air/water interface. Water acts as a dynamic magnifying glass.$

🇦🇺 YOU CAN NOW WALK THROUGH A REAL-LIFE LIGHT PORTAL Imagine if Pink Floyd's Dark Side of the Moon cover came to life and swallowed you whole. Lachlan Turczan just made that happen. His new piece, Lucida, is like stepping into a Stargate, getting hugged by a rainbow, and time-traveling through a laser dream, all at once. It’s not just some artsy light show. It’s a portal made of light, sound, and water that makes museums feel prehistoric. Lucida doesn’t hang on a wall; it devours the room. Source: Kloo

Water — the gentlest, the most elegant, the most benevolent. It surges with the dancers, and glimmers with the light. Funshine Culture’s journey upon water never stops. #WaterPerformance #ChineseCulture #EasternElegance #FunshineCulture

$n₁ sin θ₁ = n₂ sin θ₂ Watch this laser hit the glass-air boundary. At first, it bends out (refraction). Then... boom. Angle exceeds the critical θ_c = arcsin(n₂/n₁) ≈ 42° for glass (n≈1.5), and every photon turns back inside. No leakage. Pure total internal reflection. This is why fiber optics carry the internet across oceans without losing signal. Why diamonds sparkle like crazy. Why light can get trapped in a stream of water.$

251010 weibo live 🎂 #YANGYANG #刘扬扬 #양양 🐑: when ten and i were in italy, we got (the tattoo) together. i’ll show it to you. and it was done by a really great artist. i told him the idea i wanted, and he designed it and drew it straight away. it’s like a compass, but look, it’s not straight up, it’s slanted. because when you’re climbing up, it’ll never be a straight path. it’ll always be a slow climb, so it’s inclined. 🐑: it’s also a light. it has 2 meanings, 1 is to keep going up, 2 is light.

The nurse's head is translucent, and there's fluid and something pulsating inside, that keeps moving even after they die. Nurses also have a baby's lower face. This is only visible when light hits their head from a specific angle. Front and back view in video. #silenthill #silenthill2 #silenthill2remake

Blessed candles and holy water are what we call “sacramentals” – little sacraments that remind us of the grace, mercy, and presence of Jesus. In times of difficulty, we might light the holy candles and cross ourselves with the holy water as signs of faithful confidence in the Lord. It’s a practice well worth recovering! The Good Newsroom
