Reflection And Refraction Of Light In Mirrors

Light rays change direction when they reflect off a surface move from one transparent medium into another or travel through a medium whose composition is continuously changing.

Reflection and refraction of light in mirrors.

When light travels from one medium to another like air to glass or glass to water it does three things. Laws of reflection light incident on another medium. When light travels from one medium to another medium it either. In this type of reflection rays of light that hit an irregular object with a rough surface are reflected back in all directions.

Diffused irregular reflection is a non mirror like reflection of light. The throwing back by a body or surface of light without absorbing it is known as reflection of light. The law of reflection states that on reflection from a smooth surface the angle of the reflected ray is equal to the angle of the incident ray. A highly polished surface such as a mirror or other smooth and plane surface reflects most of the light falling on it.

The angle between the normal and the incident ray can then be measured using a protractor. A mirror image is the result of light rays bounding off a reflective surface. A ray box directing a narrow beam of light towards to mirror will reflect the light off it. Here the incident ray which is reflected along with reflected ray doesn t have the same angle to the normal as the incident ray.

Reflection and refraction are the two main aspects of geometric optics. Showing the properties of reflection total internal reflection and refraction in light reflection when light from an object is reflected by a surface it changes direction. Gets absorbed absorption bounces back reflection passes through or bends refraction when light is incident on a plane mirror most of it gets reflected and some of it gets absorbed in the medium. An image is formed when the light rays coming from an object meet at a point after reflection from a mirror or refraction from lens.

On the flip side refraction is when the light is absorbed by the medium but the direction and speed are affected. Reflection of light is either specular just like mirror or diffuse retaining the energy. In this chapter we will explore the first two. Light light reflection and refraction.

All in all reflection and refraction are two basic facts associated with light which are studied along. The images are of two types real images real images are formed when rays of light that comes from an object or source meets at a point after reflection from a mirror or refraction from a lens. Some of it bounces off some of it goes through and the rest of it is absorbed.
