It explains why you can see a clear image of yourself in a shiny flat mirror, but not in a dull rough wall. Instead, the light is reflected in all directions. However, the different parts of the rough surface point in different directions, so the light is not all reflected in one direction. The angle between the reflected ray and the normal is known as the angle of reflection. If light meets a rough surface, each ray obeys the law of reflection. The reflection of light from a flat surface such as a mirror is called specular reflection – light meeting the surface in one direction is all reflected in one direction. In the second example, if a light ray travelling along the normal hits a mirror, it is reflected straight back the way it came. the angle of reflection is 90° if the angle of incidence is 90°.the angle of reflection is 30° if the angle of incidence is 30°.The law of reflection states that the angle of incidence equals the angle of reflection, i = r. the angle of reflection, r, is the angle between the normal and reflected ray.the angle of incidence, i, is the angle between the normal and incident ray.the dashed line is called the normal, drawn at 90° to the surface of the mirror.This special angle of incidence is named after the. the hatched vertical line on the right represents the mirror Brewsters angle (also known as the polarization angle) is an angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection.When unpolarized light is incident at this angle, the light that is reflected from the surface is therefore perfectly polarized.the reflected ray is the light coming away from the mirror.the incident ray is the light going towards the mirror.When light reaches a mirror, it reflects off the surface of the mirror: Remember to use a ruler and a sharp pencil. The angle of incidence must be greater than the critical angle for the given pair of media. The light should travel from denser to rarer medium. Following are the two conditions of total internal reflection of light 1. with an arrowhead pointing in the direction that the light travels The angle of incidence corresponding to which angle of refraction becomes 90º is called critical angle.A ray diagram shows how light travels, including what happens when it reaches a surface. ANGLE OF REFRACTION: The angle which the refracted ray makes with the normal is called angle of refraction.
