IPC Notes The Behavior of Light
Light & Matter Opaque material – either absorbs or reflects all light; you can’t see through it ex) a brick wall
Light & Matter Transparent material – allows all light to pass through it; you can see through it ex) clear glass
Light & Matter Translucent material – allows only some light to pass through it; you can see through it, but not clearly ex) wax paper
Reflection & Refraction Reflection– occurs when a light wave strikes an object and bounces off The law of reflection states that a wave bounces off a surface at the same angle it strikes.
Reflection & Refraction Refraction– the bending of a wave due to a change in medium ex) a prism refracts white light into the colors of the visible spectrum
Producing Light Incandescent Light– produces light by heating a filament until it glows; very inefficient (about 80% of the energy is given off as heat) ex) typical light bulb
Producing Light Fluorescent Light– electricity is sent through a gas filled tube; more efficient ex) classroom light bulbs
Producing Light Neon Light– electricity is sent through a gas filled tube; different elements produce different colors
Producing Light Lasers– very narrow and focused light produced when identical atoms send off identical light waves ex) used in surgical tools, leveling, barcodes
Light & APPLICATIONS OF Optics
Light. What you see depends on the amount of light in the room and the color of the objects. For you to see an object, it must reflect some light back.

Properties of Light When light strikes an object it is:
All light is a form of energy. That’s because light “radiates”, or spreads out, in all directions from its source. (Such as a light bulb or star).
Vocabulary Mini-Review EM Spectrum & Light. What part of the EM spectrum is used for communication? Radio Waves.
WHAT IS LIGHT? The Zebrafish are emitting light when exposed to ultraviolet light. Salton Sea in California has algae that emit light giving it this glow.
Visible light waves. How do light waves behave when they strike an object?

Light and Color.
What is light?. Light Visible light is a form of energy that can be detected by cells in our eyes. Visible light is a form of energy that can be detected.
The electrons within atoms are the sources of all light.
Properties of Light. Electromagnetic Spectrum What is Light? wave matter or space Light is a type of wave that carries energy through matter or space.
Light OBJECTIVES How light is made and how it travels. How we see things The difference between opaque, transparent and translucent materials.
Wave Interactions Chapter 18. Properties of Waves Reflection – ability of a wave to bounce off a surface it cannot pass through –Angle of Incidence –
When light strikes an object it is:. 1) Reflected.
