What are the differences between a vector and a ray in terms of their properties and applications?

Vectors and rays are both mathematical concepts used in various fields such as physics and computer graphics.

A vector has both magnitude and direction, representing quantities like force or velocity. It can be added, subtracted, and scaled. Vectors are used to describe physical quantities in a coordinate system.

On the other hand, a ray is a line that extends infinitely in one direction from a specific point. It has a fixed origin but no defined length. Rays are commonly used in geometry and optics to represent the path of light or other forms of energy.

In summary, vectors have magnitude and direction and are used to represent physical quantities, while rays are infinite lines with a fixed origin and are used to represent paths of energy or light.
