WebA ray of light gives information about only the direction of light. It does not give information about the other characteristics of light like intensity and colour. However, a ray is a sensible representation of light in ray optics. The path of the light is called a ray of light and a bundle of such rays is called a beam of light. WebRay optics, also known as geometrical optics, is the study of simple properties of light and optical instruments by assuming that light travels in a straight line. Ray optics deals with …
