Ray (optics) - Wikipedia
WEBIn optics, a ray is an idealized geometrical model of light or other electromagnetic radiation, obtained by choosing a curve that is perpendicular to the wavefronts of the actual light, and that points in the direction of energy flow.
Light - Reflection, Refraction, Diffraction | Britannica
WEBLight - Reflection, Refraction, Diffraction: The basic element in geometrical optics is the light ray, a hypothetical construct that indicates the direction of the propagation of light at any point in space.
Light: Electromagnetic waves, the electromagnetic spectrum …
WEBElectromagnetic radiation is one of the many ways that energy travels through space. The heat from a burning fire, the light from the sun, the X-rays used by your doctor, as well as the energy used to cook food in a microwave are all forms of electromagnetic radiation.

Refraction and light bending (article) | Khan Academy
WEBThe same thing happens to a light ray when it moves from air to water, or from any fast medium to a slow medium: it bends toward the normal. Least time principle. Another way to think of this is to imagine you and your friend are racing out to a raft in the middle of a lake. You have to travel across a beach and then through the water.
