Basic Properties of Light
  • Light is energy.
  • When light is absorbed by a surface it can be
    transformed into several different forms of
    energy.
  • Light travels in a straight line from its source.
  • Knowing that light travels in a straight line
    allows us to predict how light will behave.
  • These straight lines are called rays.

  • 3. Light can be absorbed
  • Absorbed light is converted into another form of
    energy (thermal or heat).
  • 4. Light can be reflected
  • - Light will bounce off of surfaces at the same
    angle at which it hits the surface.

  • 5. Light can be refracted
  • - As light passes from one medium to another it
    changes direction slightly as a result of the
    different speed of light through different
    materials.
  • 6. Light can be transmitted.
  • - Light is able to pass through some types of
    matter.
