Simulate colors (wavelengths) of light sources, mixture of colors, color filtering of blockers and mirrors, and chromatic dispersion of glasses.

Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of rays. The ray in geometrical optics is an abstraction useful for approximating the paths along …

Jul 23, 2025 · Ray optics, also known as geometrical optics, is a branch of physics that studies the propagation of light by treating it as a collection of rays. These rays are essentially …

Jan 9, 2024 · Ray Optics or Geometrical Optics In this optics, the light is considered as a ray which travels in a straight line. It states that for each and every object, there is an image.

An understanding of refraction and basic ray optics is a critical foundation for understanding more complicated optical concepts and technologies.

You may regard it as a precursor to wave optics: the angles are approximately proportional to lateral momentum of light, and the image height is equivalent to separation of two geometric …

Finding images The image properties can be found by ray tracing on scale drawings, or from calculations with similar triangles.

Many results of geometric optics involving reflection, refraction (mirrors and lenses) are derived in a unified way using Fermat's Principle of Least Time.

Feb 21, 2025 · Ray optics is an essential concept in medical imaging techniques such as X-rays and MRI scans. These techniques use light rays to create images of the inside of the body, …

Dec 9, 2024 · Ray optics provides a fundamental framework for analyzing the behavior of light as it interacts with different surfaces and materials. By treating light as rays that follow geometric …
