![]() This means that the intensity of the resultant light gets reduced by a certain amount.Įxamples of Interference of Light 1. The destructive interference of light occurs when the two light waves meet each other out of phase. During constructive interference, the light radiations are in phase with each other, which leads to a significant increase in the intensity of the resultant light. The constructive interference of light occurs when the crest of one wave perfectly gets coincided with the crest of the other waves. The image in the plane mirror is virtual.The phenomenon of interference of light can be classified into two broad categories: 1.It means your right becomes left in the image. The image is equal in size to the object.The image formed by a plane mirror is upright (straight upward).We see images in a plane mirror when light reflected by the mirror enters our eyes. A plane mirror has a smooth and flat surface. We can see things just before sunrise and just after sunset due to the diffused reflection of light.Ī shiny surface is called a mirror.The light scatters in different directions when it shines on dust particles. This is because of the irregular or diffused reflection of light. Sunlight does not reach directly into our rooms, but we can see things in our rooms.We can turn the sunlight towards dark places by the regular reflection of light with the help of a shiny surface. ![]() Due to the regular reflection of light, we look at our image in the plane mirror.Regular and irregular reflections of light have many applications in our everyday life. The incident ray, normal ray, reflected ray at the point of an incident all lie on the same plane.Īpplications of regular and irregular reflection.The angle of incidence is equal to the angle of reflection.Such reflection is called irregular reflection. The rough surfaces of these objects reflect the rays of light in many directions. Most of the objects in the everyday world are not smooth on the microscopic level. The reflection by these smooth surfaces is called regular reflection. For example, a smooth surface of silver reflects the ray of light in one direction only. The nature of reflection depends on the smoothness of the surface. Now we know that light has dual nature wave as well as particle nature. In 1900, Planck suggested that light consists of small packets of energy called photons were confirmed by experiments. In 1802, Thomas young proved the wave nature of light experimentally. Maxwell formulated the wave theory of light. According to him, light consists of tiny, fast-moving particles. Newton put forward the idea of the corpuscular nature of light. In the early 1700 s, were two ideas about the nature of light particle nature and wave nature. Because almost no light is reflected by the printed words, we “see” them as black areas. Reflection of light is defined as: “When light traveling in a certain medium falls on the surface of another medium, a part of it turns back in the same medium.”We see a page of a book because light reflects from each part of the page in all directions so that some of the light rays from each part of the page enter our eyes. The number of things you see in a day is due to the reflection of light.We see nonluminous objects due to the reflection of light. ![]()
