WebLight Rays and Beams. A ray of light is the direction along which the light energy travels. In practice a ray has a finite width and is represented in diagrams as straight lines. A beam of light is a collection of rays. A search light emits a parallel beam of light (Fig.a). Light from a lamp travels in all directions which is a divergent beam. Webincident angle. angle of refraction. angle of reflection. 24. Consider these indices of refraction: glass: 1.52, air: 1.0003, water: 1.333. Put these materials in order from the one in which the speed of light is fastest to the one in which it is slowest. The speed of light in water > the speed of light in air > the speed of light in glass.
