Visible light waves

How do light waves behave when they strike an object?

goes nowhere.

passes through.

Light waves vocabulary• Opaque:

Light waves vocabulary• Opaque: Light does not pass

through. Light is either absorbed or reflected.

• Translucent:

Light waves vocabulary• Opaque: Light does not pass through.

Light is either absorbed or reflected.• Transparent: Light passes straight

through an object.• Translucent: Light passes through an

object but objects on other side are blurred / jumbled.

                                          

Black Paper

                                          

Black Paper

The paper is considered opaque.

Light was absorbed.

                                          

Mirror

                          

                                          

Mirror

                          

The mirror is opaque.The light is

reflected.

                                          

Window

                                                    

                                          

Window

                          

The window is transparent.The light is

transmitted.

                                                    

                                          

Wax-paper

                                                    

                                          

Wax-paper

                          

The wax-paper is translucent.

The light is transmitted but “jumbled”.

                                                                                       

Reflection vs. Refraction

Reflection vs. Refraction

• Light bouncing off of a surface.

Reflection vs. Refraction

• Light bouncing off of a surface.

• Light bends because it changes speeds as it changes mediums.
