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.

Reflection and refraction of light in mirrors.

Light light reflection and refraction. 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. In this type of reflection rays of light that hit an irregular object with a rough surface are reflected back in all directions.

Here the incident ray which is reflected along with reflected ray doesn t have the same angle to the normal as the incident ray. When light travels from one medium to another medium it either. All in all reflection and refraction are two basic facts associated with light which are studied along. On the flip side refraction is when the light is absorbed by the medium but the direction and speed are affected.

Reflection and refraction are the two main aspects of geometric optics. 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. We will explore what rules govern them their technical names and then apply these rules to study the beautiful world of curved mirrors and lenses. 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. 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. Reflection of light is either specular just like mirror or diffuse retaining the energy. In this chapter we will explore the first two.

There the incident initial ray strikes the mirror a normal line needs to be drawn the normal line is a perpendicular line to the mirror. A ray box directing a narrow beam of light towards to mirror will reflect the light off it. A highly polished surface such as a mirror or other smooth and plane surface reflects most of the light falling on it. 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. Reflection is when the light goes back to the previous medium but changes direction.
