简介
A bright yellow light ray strikes a mirror and reflects at an equal angle. The normal line and labeled angle arcs illustrate the law of reflection. A curved mirror then shows how parallel rays converge to a focal point.

Light Reflection
Description
A bright yellow light ray strikes a mirror and reflects at an equal angle. The normal line and labeled angle arcs illustrate the law of reflection. A curved mirror then shows how parallel rays converge to a focal point.
Phases
| # | Phase Name | Duration | Description |
|---|---|---|---|
| 1 | Flat Mirror Setup | 2s | Vertical mirror line appears with normal (dashed) |
| 2 | Incident Ray | 2s | Yellow arrow travels toward mirror |
| 3 | Angle Labels | 2s | Angle of incidence and reflection arcs appear |
| 4 | Reflected Ray | 2s | Reflected yellow arrow leaves mirror |
| 5 | Curved Mirror | 3s | Curved mirror with parallel rays converging |
