Radiation and Thermal Energy

Our Model of the Atom Evolves




Observations
Observations? transfer mechanism?


Incandescent light bulb
Incandescent light bulb transfer mechanism?

  • Watch carefully as the power delivered to the light bulb is increased.

  • Write down your observations.


Incandescent light bulb1
Incandescent light bulb transfer mechanism?

  • Now view the light bulb through a spectrometer as the power delivered to the bulb is increased.

  • Write down your observations


Compact fluorescent light bulb
Compact fluorescent light bulb transfer mechanism?

  • Watch carefully as the power delivered to the light bulb is increased.

  • Write down your observations.

What is the difference
What is transfer mechanism?the difference?







Our current model of the atom
Our current model of the atom…. atomic level.

  • Does not account for these differences in structure, therefore we need a model of the atom with some more internal structure that can account for the radiation emitted by atoms.
