Visible Light (physics only)

• What is the visible light spectrum?

  Light visible to the human eye
• How does each color within the visible light spectrum behave?

  Each color has its own wavelength and frequency
• What do color filters do to certain wavelengths of light?

  They absorb certain wavelengths and transmit others
• How is the color of an opaque object determined?

  By the wavelengths of light that are reflected
• What happens to wavelengths of light that are not reflected by an object?

  They are absorbed by the object
• What color does an object appear if all wavelengths are reflected equally?

  The object appears white
• What color does an object appear if all wavelengths are absorbed?

  The object appears black
• What types of objects transmit light?

  Transparent or translucent objects
• What is a perfect black body in terms of light?

  It absorbs all wavelengths of light
• What are the properties of a perfect black body?

  • Absorbs all wavelengths of light
  • Reflects no light
  • Transmits no light
