What do rays emanating from a point source of light do?

Rays emanating from a point source of light diverge as they move away from the source. This is due to the nature of light traveling in straight lines. When light is emitted from a single point, the rays spread out in all directions, creating a conical shape. This behavior is intrinsic to point sources, which do not focus light into parallel lines but instead allow the light to scatter.

In the context of optics, divergence is characteristic of light spreading out after leaving the source. In practical applications, this divergence can be observed when considering light bulbs or stars, where the light travels outward into the environment rather than converging to a focal point. Understanding this concept is crucial for various areas in physics and engineering where light behavior is significant, such as in lens design, optical instruments, and astronomy.

The other options relate to distinct behaviors of light. For example, convergence applies to light rays that meet at a point, which typically occurs with lenses or mirrors that focus light. Refraction refers to the bending of light as it passes through different media, and reflection involves bouncing back of light when it strikes a surface. Thus, while these terms describe important optical phenomena, they do not accurately describe the immediate behavior of rays from a point source of
