In optics, a ray is an idealized geometrical model of light or other electromagnetic radiation, obtained by choosing a curve that is perpendicular to the wavefronts of the actual light, and that points in the direction of energy flow.

Light Rays are nothing but a model explaining the movements of Light from one point to another. A group of Light Rays or a Light Beam, coming out from a source of Light is known as a point source. Beams of Light can be of 3 types. They are parallel, convergent and divergent.

2025年3月13日 · Light - Reflection, Refraction, Diffraction: The basic element in geometrical optics is the light ray, a hypothetical construct that indicates the direction of the propagation of light at any point in space. The origin of this concept dates back to early speculations regarding the nature of light.

光线追踪 是用于计算 点与点之间可见性 的一种技术。 Light transport algorithms 是用来模拟 光在空间中的传播方式 (当与物体相互作用时)。 简言之， 它们用于计算场景中某个点的颜色。 不要将光线追踪与light transport algorithms 混淆。 他们是两个不同的东西。 光线追踪不是 light transport algorithms 。 它只是一种计算点之间可见性的技术。 光线追踪是关于光线（rays）的，光线是本文的主要主题之一。 众所周知，光栅图像（raster image）是由像素组成的。

A straight line that originates at some point is called a ray. The part of optics dealing with the ray aspect of light is called geometric optics. Light can travel in three ways from a source to …

Full spectrum colour, flawless colour rendering, flicker free lighting with no blue spike in the colour spectrum. We’re striving to bring healthy lighting to everyone. What does RAY do? The RAY C35 E14 in the Crystal Clear finish is the best way to get maximum lighting for a modern and contemporary fixture.

关于你说的翻译上的区别，我想IdeaRay可以翻译成思想放射，或者思想射线了，而idea light 则可以翻译成思想之光。 想要表示思想之光的话，light of wisdom、thought、thinking、light都是符合文法的。而WISDOM表示的是智。可以理解为智慧之光

The ray model of light describes the path of light as straight lines. The part of optics dealing with the ray aspect of light is called geometric optics. Light can travel in three ways from a source to another location: (1) directly from the source through empty space; (2) through various media; and (3) after being reflected from a mirror.

The ray nature of light is used to explain how light refracts at planar and curved surfaces; Snell's law and refraction principles are used to explain a variety of real-world phenomena; refraction principles are combined with ray diagrams to explain why lenses produce images of objects.

2024年3月12日 · We will instead spend most of our treatment of optics making use of a simpler model of light, the ray model, which does a fine job in most practical situations. Not only that, but we will even backtrack a little and start with a discussion of basic ideas about light and vision that predated the discovery of electromagnetic waves.
