• Light & Shadows
• Reflection/Scattering
• Transmission
• Absorption
• Color

LIGHT

• Light bounces off from the object to the eye
• To see an object you need:
• A clear and straight parh
• An eye
• A light source and light

SHADOW

• A shadow does not have any light in it
• You can see the object and the shadow

REFLECTION

• Light bounces off in a V angle
• The surface is microscopically smooth
• The numbers are either very low or very high

SCATTERING

• The numbers are unpredictable (random)
• The surface is not microscopically smooth

TRANSMISSION /OPAQUE

• Transmitting is when light goes through a substance
• Transparent is when most or all of the light goes through e.g window
• Transluscent is when some of the light goes through e.g your skin
• Opaque is an adjective that describes light not transmitting through an object

Absorption is when an object uses light in order to use as energy.

RODS/CONES

• There is three main cones in your eyes
• Rods control lightness and darkness
• The more amount of light, the brighter the color
• Black is not a color (0% light)
• Refraction is the process of bending light
