It is important to understand that the ray and beam are artificial constructs. It says nothing about what kind of beam the light is. A ray is the course of the path taken by light.
A beam is a stream of light energy and may be represented by a number of rays that might be diverging, converging or parallel. Examples of each of these will be met within due course.

The concept of ray is only applied to the light. A light is not considered as a wave in the ray theory of light. Therefore, wave related phenomena such as scattering, diffraction, and interference cannot be described using the ray model. There are a few special types of rays are termed based on the place it occurs. A light ray, which falls on an object, is known as the incident ray; a light ray that is reflected by an object is known as the reflected ray, and a light ray that is refracted by an object is known as refracted ray.
A beam is a narrow projection of a set of particles or waves. There are two main types of beams. Those are light or electromagnetic beams and particle beams. Beams are used in various fields and applications.
