Would the result be different if instead of having a half circle we had a whole circle? In any case, nice demonstration, especially if we take a little height, and transpose to our planet and the sun (for example) ...

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.

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

Total Internal Reflection Air has a lower index of refraction than the water/glass so the probability of a photon being found outside of the barrier is almost zero.

The natural fibers of ulexite act as optical fibers, transmitting light along their long axes by internal reflection. When a piece of ulexite is cut with flat polished faces, it will display an image of whatever surface is adjacent to its other side.

A laser can ride a falling stream of water. Shine it through a hole in a milk-clouded soda bottle and the beam stays trapped by total internal reflection, the same physics as fiber optics, just liquid and gravity doing the guiding.

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).

Vegetable Oil and Pyrex have the same refractive indexes of 1.47. When light travels through the glass and then the oil, the speed of light slows down and on reflection, makes the glass seem invisible.

n₁ sin(θ₁) = n₂ sin(θ₂) This elegant equation describes how light bends at the boundary between two media. Here, n₁ and n₂ are the refractive indices, while θ₁ and θ₂ are the angles of incidence and refraction measured from the surface normal. As light rays obey this simple trigonometric relationship, beautiful caustic curves emerge and focal points shift with every change in geometry or material. It is pure geometric optics at its finest: the raw interaction of light and matter, reminding us that the universe is governed by beautiful, predictable symmetries. This is used while designing high-resolution camera lenses (correcting aberrations for sharp focus) and enabling fiber-optic communication through total internal reflection.
