## BIG IDEAS - Reflection is the bouncing back of light - Reflection helps us see objects. - Luminous objects produce light - We cannot see non-luminous objects without light ### Ray Diagrams - Incident ray – the ray that strikes the surface - Reflected ray – the ray of light that leaves the surface - Point of incidence – the point where a ray of light strikes the surface - Normal – a perpendicular line drawn from the point of incidence - Angle of incidence – the angle between the incident ray and normal - Angle of reflection – the angle between the reflected ray and normal ### Law of Reflection - The angle of incidence is equal to the angle of reflection. ![[Law of Reflection.png]] --- Return [[Home|Home]] | [[Oscillations]] | [[Electromagnetic radiation]] | [[Module 5 Electromagnetic Spectrum]]
