Concept of Reflection and Laws of Reflection Concept of Reflection The idea that light travels in straight lines is uppermost, while its wave character and other physical aspects are disregarded. Since the laws of reflection and refraction corollaries of the wave nature. Sources of light, such as the sun, stars, and electric lamps can be seen when the light they produce reaches the eyes. However, most objects can only be seen when light is reflected off the surface of an object. An object that reflects no light appears to be black. On the other hand, an object that reflects all of the light appears the same color as the light source, for instance, something which reflects all of the white light reaching it from the sun appears white light mirrors and highly polished surfaces, reflect light strongly and we shall now deal with the laws governing the reflection. Laws of Reflection The illustrates the terms that we use in the study of reflected light. Laws of reflection Represents the surf
