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.

Laws of Reflection and Plane Mirror Images. Reflection When light strikes a surface, some is absorbed, the rest bounces off the surface. This is called.
Reflection and Refraction of Light. Reflection We see objects because light bounces off them. This ‘bouncing off is known as Reflection. For example:
Ray Diagrams & Reflection Images in plane mirrors.
Light rays and the laws of reflection help determine how and where an image is formed in a plane mirror. REFLECTION is the bouncing back of light.

Conceptual Physics Notes on Chapter 29 Reflection & Refraction.
Line Ray Beam the paths along which light energy travels a bundle of light rays.
Geometrical optics The Sun is our natural source of light. Objects such as the sun, a light bulb, a fire, which give off their own light are called.
Plane Mirrors. The Laws of Reflection The angle of reflection always equals the angle of incidence The incident ray, normal, and reflected ray all.
Plane Mirrors SNC2P – Optics. Plane Mirrors Mirrors reflect in predictable ways. As the angle of incidence (i) increases, the angle of reflection (r)
Properties of Reflective Waves Flat Mirrors. Light travels in a straight line Some light is absorbed Some light is redirected – “Reflected”
Plane mirror: a regular, flat mirror like those used in bathrooms, in cars, by dentists, etc. A mirror is just a reflective surface (made of a thin sheet.
PW2 - Reflection. The angle of incidence is equal to the angle of reflection. The incident ray, reflected ray, and normal all line in the same plane.

The incident ray and the reflected ray behave in predictable ways, which leads to the two laws of reflection: 1.The angle of incidence equals the angle.

OBJECTIVE At the end of this lesson, you should be able to: –Describe the characteristic of the image formed by reflection of light. –Solve problem involving.
Reflection: What is it? Reflection occurs when light bounces off an object. Reflection allow our eyes to see the world around us!
Reflection Objectives: 1.Describe how light reflects off rough and smooth surfaces. 2.Explain the law of reflection.
Some mirrors are curved. These give distorted images. If a mirror curves inwards then it is a concave mirror; if it curves outwards it is a convex mirror.
