The bouncing off of light as it hits a surfaceReflection of Light The bouncing off of light as it hits a surface
Types of Reflection Regular Reflection a.k.a. specular reflectionWhen parallel rays are reflected parallel Reflecting surface is smooth
Types of Reflection Irregular Reflection a.k.a. diffuse reflectionWhen parallel rays are reflected in different directions Reflecting surface is not perfectly smooth
Important Terms Object Image The source of lightThe picture of the object that is formed from the reflected rays
Important Terms image object
Important Terms Incident Ray Reflected Ray NormalLight ray that hits a surface Reflected Ray Light ray that bounces off the surface Normal Line that is perpendicular to the reflecting surface
incident ray normal reflected ray mirror
Important Terms Angle of incidence Angle of reflectionAngle between the normal and the incident ray Angle of reflection Angle between the normal and the reflected ray
incident ray Angle of incidence normal Angle of reflection reflected ray mirror
#1 The angle of incidence equals the angle of reflection.Laws of Reflection #1 The angle of incidence equals the angle of reflection.
Laws 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:

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 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.
Unit 4 Optics: Properties of Light and Reflection
A Brief Look at LIGHT. Light usually travels 4 only in a straight line. 4 This is known as the... Law of Rectilinear Propagation.
Laws of Reflection From the Activity you performed, when you shine an incident light ray at a plane mirror, the light is reflected off the mirror and forms.

Reflection: What is it? Reflection occurs when light bounces off an object. Reflection allow our eyes to see the world around us!
Types of mirror When we draw a ray diagram we represent a mirror by drawing a line with dashes on the silvered (non-shiny) side. Most mirrors are flat.
