Ray

1. Parallel Beam of light: When the group of rays are parallel to each other such beam of light is called a parallel beam of light.
2. Convergent Beam of light: When the group of rays are not parallel to each other but are converging at a point such beam of light is called a convergent beam of light.
3. Divergent Beam of light: When the group of rays are not parallel to each other but are diverging from a point such beam of light is called a divergent beam of light.
4. Diffused Beam of light: When the group of rays are not parallel to each other but are intersecting each other such beam of light is called a diffused beam of light.
