Slide 2 Light Slide 3 A light source produces light. Slide 4 Sources of light Slide 5 What happens when light hits an object? The light is reflected off the object. Slide 6 We see things because of reflected light. Slide 7 We blue because blue is reflected; white because all colors are reflected. Slide 8 We see ourselves in a mirror because of reflection. Slide 9 The light that hits an object is called the angle of incidence. The light that bounces off the object is called the angle of reflection. Slide 10 Angle of incidence = Angle of reflection Molecular Expressions Slide 11 This is called the law of reflection. Molecular Expressions Slide 12 Click here for Reflection video clip. Slide 13 When light passes thru transparent objects (water, glass, etc.), the light is refracted (bent). Slide 14 When light passes thru water, its refracted. Slide 15 When light travels thru a prism, the refraction forms the spectrum.

Slide 21 If the object is transparent, it will pass through it. Slide 22 If the object is translucent, light is diffused as it passes through it.
