The light waves bounce off these surfaces at a definite angle. Specular surfaces are smooth and shiny, like a mirror. Diffuse reflection is responsible for the image we see in a mirror. The light waves hit the rough surface and bounce off in different directions. It happens when the surface is not smooth. In diffuse reflection, the light that hits an object is scattered in many directions. They differ based on the type of object and angles created by the light. There are three types of reflection of light. Similarly, you can also see your reflection on your phone’s screen. When light reflects off the smooth surface of the water, it produces a clear image. The angle between the incoming and reflected light waves is the same.Īnother typical example of reflection is the surface of a still pond or lake. It happens because light waves change direction when they bounce off a mirror. However, you must have noticed that a mirror shows a left-right reversal of the image.
The most common example of reflection is a mirror. When light reflects off a concave surface, it forms a real image. Light waves reflecting off a surface can produce specific effects. The waves reflecting off the curved surface interfere with each other, producing a distorted image. When light waves hit a curved surface, they bounce off at different angles. Mirrors reflect light in a straight line. For example, a smooth, shiny surface reflects more light than a dull, rougher surface. The amount of reflected light also depends on the nature of the reflecting surface. The angle between the light that hits the surface, and the angle of the reflected light waves determine how much reflected light we see. When light waves bounce off a surface, we see a reflection. Overview of Reflection Image Credit: 12019, Pixabay We also describe the applications of reflection and refraction in our everyday lives. The guide below explains the difference between both phenomena. Likewise, when photons pass through an object, they refract the light. That’s why you can see your reflection in a mirror. When photons bounce off an object, they reflect the light. Light consists of tiny particles called photons. Reflection happens when light bounces off an object, and refraction occurs when light passes through an object. Each individual reflection still obeys the law of reflection, but the different parts of the rough surface are at different angles.Refraction and reflection are characteristics of light that often confuse people. This may cause a distorted image of the object, as occurs with rippling water, or no image at all. Instead of forming an image, the reflected light is scattered in all directions. If a surface is rough, diffuse reflection happens. A ray diagram showing how an image forms in a plane mirror Diffuse reflection In a virtual image, the rays appear to diverge from behind the mirror, so the image appears to come from behind the mirror. This is the type of reflection that happens with a flat mirror. Reflection from a smooth, flat surface is called specular reflection. The diagrams show a water wave being reflected at a barrier, and a light ray being reflected at a plane mirror. The angles of incidence and reflection are measured between the light ray and the normal - an imaginary line at 90° to the surface. The reflection of sound causes echoes.įor example, if a light ray hits a surface at 32°, it will be reflected at 32°. Waves - including sound and light - can be reflected at the boundary between two different materials.
