To better understand how the atmosphere produces these bursts of color, we need to understand a little something about light. Some of these optical effects include halos, sun pillars, and sundogs. The atmosphere is also capable of producing colorful displays when conditions are right. The atmosphere does more than just produce our daily weather: from sunny to cloudy days, dry to wet, stormy to snowy. The image in the plane mirror is virtual.How are Halos, Sundogs and Sun Pillars Created?.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 angle that reflected ray forms with the normal is called the angle of reflection. The incident ray forms an angle of incidence with the normal. The line perpendicular to the point of incidence is called normal. The point at which incident ray strikes is called the point of incidence. The ray that bounces off is called a reflected ray. The ray that strikes the shiny surface is called an incident ray. Reflection occurs when a light ray strikes a shiny surface(mirror) and bounces off. 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.
