WebJun 19, 2024 · 1 Answer. Vector and ray are symbolized the same way: a line segment with an arrow on one end but they are very different things. A vector has a direction and a magnitude (for example, 5 km south-east). A ray has just a direction and a starting point, … A light ray is a line (straight or curved) that is perpendicular to the light's wavefronts; its tangent is collinear with the wave vector. Light rays in homogeneous media are straight. They bend at the interface between two dissimilar media and may be curved in a medium in which the refractive index changes. Geometric optics describes how rays propagate through an optical system. Objects to be imaged are treated as collections of independent point sources, each producing spherical …
