Light waves vocabulary• Opaque: Light does not pass
through. Light is either absorbed or reflected.

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.
