Ray optics book back questions
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.

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. WebThe phenomenon of the light returning to the same medium from which it started after striking a surface is known as a reflection of light. There are two laws of reflection as follows.
