visible light

• Specular reflection


  Reflection where light rays reflect in a single direction, producing an image
• Diffuse reflection


  Reflection where light rays are scattered, not producing an image
• White light


  A mixture of all the different colors of visible light
• Splitting white light through a prism


  Produces a spectrum of visible light colors
• Color of an object


  Depends on which wavelengths of light are reflected, transmitted or absorbed
• Colored filters


  Absorb specific wavelengths and transmit others
• Transparent objects


  Allow light to pass through clearly
• Translucent objects


  Scatter light, cannot see through clearly
• Opaque objects


  Do not allow light to pass through
• White object


  Reflects all wavelengths of visible light equally
• Black object


  Absorbs all wavelengths of visible light
• Colored object


  Absorbs all wavelengths except the color it reflects
• Colored object under colored filter


  Only the color that is both reflected by the object and transmitted by the filter is seen
