- Ray-tracing diagrams are used in geometric optics, where light is treated as rays that travel in straight lines and change speed and/or direction as they pass through different transparent media.
- The purpose of a ray-tracing diagram is to illustrate optical phenomena such as absorption, dispersion, polarization, reflection, refraction, scattering, and transmission.
- The accuracy of a ray-tracing diagram depends on the quality of the data used to create it, such as the refractive index of the materials and the angles of incidence and reflection.
- Ray-tracing can be used to design and optimize optical systems, such as lenses and mirrors.
