Answer 1

Ray refers to any set of lines passing from one point.

Explanation:

In different studies, ray has different meanings. For example, in geometry ray refers to a straight line that starts from a point and has no end.

It also refers to a beam of light, heat, or any other visible or tangible form of radiation. A ray can be straight or bent in various directions due to various objects that come in between the ray.

Rays are generally formed due to scattering of atoms of any object which results in a weaker bond.

Answer 2

Answer:

In optics a ray is an idealized geometrical model of light, obtained by choosing a curve that is perpendicular to the wavefronts of the actual light, and that points in the direction of energy flow.
