Snell's law: light bends toward the normal in glass
A light ray travels from air into glass, bending according to n1 sin(theta1) = n2 sin(theta2). As the incident angle sweeps through 45, 75, and 10 degrees, the refracted angle updates live, showing how the ray bends because light slows down inside denser media (v = c/n). The animation then reverses the path, illustrating total internal reflection when light exits glass beyond the critical angle. Useful for physics students learning optics and wave behavior.

The prompt that made it
Apply ALL of the following review notes precisely; keep everything else identical. This video is for social media and must be impeccable. - Video looks good but the green angle is drawn in the wrong side
Make the next one in this series
- Show how the critical angle changes when switching from glass to water as the denser medium
- Animate a prism separating white light into colors using wavelength-dependent refractive index
- Visualize fiber optic cables using repeated total internal reflection to guide light signals
