1. In mathematics, a ray is usually defined as a line segment that starts from a point and extends infinitely in one direction. This definition emphasizes the infinite length of a ray, that is, the ray can extend infinitely along its direction. This feature makes ray have a special position and function in many mathematical problems. In functional analysis, rays are also used to study the convergence and continuity of functions.
2. In physics, the infinite length of rays also plays an important role. For example, in quantum mechanics, particles can travel in the form of waves, and waves can be regarded as infinitely long rays. This infinite length makes rays have a special position and function in quantum mechanics, and the state and behavior of particles can be described by wave functions.
3. Infinite length of ray also plays an important role in engineering. For example, in architecture, architects can use infinite light to design buildings with special shapes and functions. For example, in bridge design, architects can use the infinite length of rays to design bridges with beautiful curves and complete functions.

1, ray is a ray in geometry, which refers to a straight line extending infinitely from one end of a line segment. One end of it is fixed and the other end extends indefinitely, so it is impossible to measure the length. Light has a beginning, but no end. It can extend infinitely along its extension direction, which is called ray direction. The direction of light determines its shape and use.
2. Ray is widely used in mathematics, physics and engineering. In mathematics, light can be used to indicate the direction of vectors and point sets. In physics, rays can be used to describe the propagation of particles and the intensity and direction of radiation. In engineering, rays can be used for measuring and drawing, and also for designing buildings and mechanical structures.
3. The representation of the ray is to draw an arrow at the starting point to indicate the direction of the ray. If you need to express the length of the ray, you can choose a point on the ray, connect the starting point with the point with a line segment, and mark the length on the line segment.
