After opening the page, an optical experiment scene will be displayed, including optical elements such as light sources, prisms, and lenses. Light is dispersed when it passes through a prism and breaks down into a rainbow spectrum; it is focused or diverged when it passes through a lens. You can drag the optical element to change position.

The whole process is purely front-end animation, based on Canvas 'ray tracing algorithm, and calculates the path of each ray in real time. Smooth interaction and accurate physical effects.

Suitable for being used as a physics teaching aid, popular science display, or purely appreciating the beauty of optics. The realization principle is the combination of Snell's law and geometric optics.

Optics Lab is an interactive visual effect that simulates light refraction, reflection and dispersion, based on Canvas real-time rendering.
