Hint: Let us first get some idea about light. Light, also known as visible light, is electromagnetic radiation that falls within the portion of the electromagnetic spectrum that the human eye can detect. Between the infrared and ultraviolet, visible light is classified as having wavelengths in the \[400-700\] nm range.

Complete step by step answer:
A light ray is a straight or curved line perpendicular to the wavefronts of light, with its tangent collinear with the wave vector. In a homogeneous medium, light rays are straight. They bend at the interface of two dissimilar media and can also be bent in a medium with a changing refractive index.
A light beam, also known as a light beam or a light beam, is a directional projection of light energy emitted by a light source. When sunlight is filtered through clouds, trees, or walls, it creates a light beam (a sunbeam).

So from the image we can simply say that,
A ray of light is the direction or path along which light energy passes in a medium. A straight line with an arrow on it is used to reflect it.
A beam of light is a set of light rays emitted from a single source.

Note: We see the beam because the air contains a lot of dust particles, and some of the light bounces off of them and travels in different directions, including toward you. While photons can bounce off each other, visible photons in a vacuum or air are extremely unlikely to do so.
