![]() ![]() It refers to the shift in direction and speed of the beam of light waves, because of the change in the transmission medium. Refraction is the phenomenon of light, in which the wave is diverted when it passes diagonally through the interface between two media of different densities. Irregular reflection: Irregular reflection also termed as diffuse reflection, which occurs when the beam of light falls on the rough surface and reflects light in various directions. Regular reflection: Regular reflection is also termed as specular reflection, which occurs when the beam of light falls on a regular, polished, and smooth plane. The ray of incidence, the ray of reflection, and the normal drawn at the point of incidence, to the mirror, occurs on the same plane.The angle of incidence is identical to the angle of reflection.It changes the direction of the beam of light when it falls on the plane so that the ray goes back to the medium, in which it is generated. In simple terms, reflection implies the rebounding of light, sound, heat, or another object back to the source, without absorbing it. In refraction, the angle of reflection and angle of incidence are not the same.Īs we have seen the difference between reflection and refraction, let us now discuss some more details regarding reflection and refraction. The angle of reflection and angle of incidence is the same in the case of reflection. The angle of Reflection And Angle of Incidence The medium in which light propagates remains the same. The speed of light varies with the medium in which the ray undergoes bending. When a light ray strikes the boundary of a shiny surface the speed of light ray does not vary. In this process, light changes path i.e travels from one medium to another. In this process, light bounces back and returns back in the same direction. There are two forms of reflection, they are, Regular reflection (Specular reflection) and Diffused reflection. ![]() This occurs in transparent surfaces that allow bending of the ray to a different medium. Generally occurs on shinny surfaces that only allow rebounding of light without permitting penetration through it. Refraction is the bending of light rays when it travels from one medium to another. ![]() Reflection is the bouncing back of light when it strikes a smooth surface. The important difference between reflection and refraction: Parameters Diffraction is not a part of retro reflectivity, but is a part of the manipulation of light.Difference between reflection and refraction Refraction is a part of reflectivity in that bending light is an element of that process. Retro Reflectivity is a form of reflection that returns light from a surface, but only back to the source of the light. Glass of water with a fork in it (refraction) Light shining through a small hole (diffraction)ĩ. Light beams around a cloud (diffraction)ħ. Here are some examples of Reflection and Refraction:Ĥ. What happens to light when you shine it through an aperture or the edge of a solid object is diffraction. What happens to light when you shine it through a glass of water is refraction. What happens to light when you shine it on a mirror is reflectivity. The sun behind a cloud and the rays that result are an example of diffraction. The distortion of a pencil in a glass of water, a mirage in the desert, or light through a glass lens, are examples of refraction. Reflection, refraction, and diffraction change the direction of light, but in different ways.Ī mirror, like the one on your car or in your master bath is an example of reflectivity. In diffraction, light is both spread out, and its direction is changed. Diffraction is the process by which a beam of light is spread out as a result of passing through a narrow aperture or across an edge. In other words, refraction is the bending of light as it passes though a medium, while reflection is the return of that light. In refraction, the waves go through a clear medium, and as they travel though, their speed and direction are altered. In reflection, the light rays striking a surface return towards the originating source of light as the waves spring or bounce off the surface. The difference between light reflection, light refraction, and light diffraction is simple. ![]()
