Reflection of Light The bouncing off of light as it hits a surface
Types of Reflection Regular Reflection –a.k.a. specular reflection –When parallel rays are reflected parallel –Reflecting surface is smooth
Types of Reflection Irregular Reflection –a.k.a. diffuse reflection –When parallel rays are reflected in different directions –Reflecting surface is not perfectly smooth
Important Terms Object –The source of light Image –The picture of the object that is formed from the reflected rays
Important Terms object image
Important Terms Incident Ray –Light ray that hits a surface Reflected Ray –Light ray that bounces off the surface Normal –Line that is perpendicular to the reflecting surface
mirror normal incident ray reflected ray
Important Terms Angle of incidence –Angle between the normal and the incident ray Angle of reflection –Angle between the normal and the reflected ray
mirror normal incident ray reflected ray Angle of incidence Angle of reflection
Laws of Reflection #1 The angle of incidence equals the angle of reflection.
#2 The incident ray, the reflected ray and normal all lie in the same plane. This means they can all be drawn on a flat sheet of paper.
