![]() Refraction is the process in which when the incidence ray strikes the surface in some medium and it gets diverted or bent while passing through the medium. The angle in between the incident ray and the normal ray is known as an angle of incidence and the angle which is between the normal ray and reflected ray is known as the angle of reflection. The ray which reflects back that too from a smooth surface is known as a reflected ray. ![]() In the process reflection, the ray which strikes the smooth surface is known as the incident ray. ![]() This implies to us that the denser the medium, light travels at a slower speed and vice versa.Īngles of Incidence, Reflection, Refraction It determines very clearly that the speed of a ray of light in the new medium. The process of refractive index is the ratio of the angle of incidence to the angle of refraction. On the other hand, the process of refraction is the phenomenon of bending rays of light towards a different medium after interacting with the boundary of that medium. The crucial difference between refraction and reflection is that reflection is the act of the rebounding of the wave of light in the same medium after striking the boundary of a medium which is different. Reflection and Refraction are the two major phenomena which are related to the propagation of beams of light. It refers clearly to the shift in speed and the direction and speed of the beam of the wave of light this is because of the change in the medium of transmission. In this phenomenon, the wave is diverted when it passes diagonally through the interface which is between two media of different densities. Examples of this phenomenon we can take as refraction are lenses, prism, and telescopes. Refraction: The change of speed of light and the direction as it enters from one medium to another is termed as the refraction of light. Irregular Reflection: The reflection which is Irregular also termed as diffuse reflection occurs when the beam of light falls on the rough surface and then the light reflects in various directions. Regular Reflection: The reflection which is regular is also termed as specular reflection occurs when the light beam falls on a regular and polished plane which is smooth. In other words, we can easily say that the reflection is the bouncing back of the light rays from a surface that is in the same medium. Reflection: When a light ray that comes back into the same medium after striking the surface of another medium, then the phenomenon is known as the reflection of light. Let us now discuss what is the difference between refraction and reflection. When light passes through different mediums, of two different phenomena happen. The direction in rays of light change when they reflect from a surface and when they travel from one transparent medium into another or travel through a medium whose composition is continuously changing. ![]() How much a wave is refracted is said to be determined by the change in the speed of the wave and the initial direction which is of wave propagation relative to the change in the direction and in speed.ĭifference Between Reflection and Refraction of Light In physics, we have seen that refraction is the change in direction of a wave that is passing from one medium to another medium or from a gradual change in the medium. The very common examples that include the lights reflection water and sound waves. The phenomenon that is of reflection is said to be the change in direction of a wavefront that is at an interface which is in between two different media.
