The direction of the path taken by light is called

Answer Details

The term used to describe the direction of the path taken by light is "ray." A light ray is a thin beam of light that travels in a straight line from its source. The direction of the ray is determined by the angle at which it is emitted from the source. When the ray encounters a surface, it may be reflected, refracted or absorbed, depending on the properties of the surface. The other options, "locus," "lines," and "beam," do not accurately describe the direction of light. "Locus" refers to the set of all points that satisfy a particular condition, and "lines" can refer to a variety of things but does not specifically describe the direction of light. "Beam" refers to a group of rays, rather than the direction of a single ray. Therefore, the correct answer is: Ray.
