Article for question 10:
 
From our reference tables:
 
 
 
There is just not enough energy present at fixed temperatures to elicit high frequency radiation because the oscillators (electrons and atomic nuclei) are taking in the energy in constant chunks (photons) and re-emitting these photons. The energy is not a constant flow and does not build up. 
 
The heater in the Black Body radiator makes the atoms vibrates at all different frequencies and thus a wide range of photons are released because temperature is proportional to molecular motion range.
 
 The lower energy vibrations use up the energy first, leaving very few chunks or quanta to excite  the higher energy vibrations.  The higher energy vibrations (at the smallest wavelengths) are needed to elicit higher frequency radiation and there is just not enough of these photons available.
 
With classical physics, energy is a continuous stream of energy, and oscillators in the black bodies can vibrate with ANY frequency thus have an infinite amount possible frequencies or modes. Classical physics suggests that kinetic energy that is absorbed is absorbed evenly throughout every possible mode (or frequency ). This is called the Equal Partition Theorem and this theory work very well in many cases to predict kinetic energy in many systems.  It did NOT do very well in the explanation of wavelengths emitted from black bodies. Its formulas (of equal partition called the Rayleigh Law) led us with predictions that led to the “catastrophe” because energy that was absorbed by the black body was absorbed equally by all modes of vibration. Because there are more vibrational modes that are smaller (limit to zero) these high frequency modes would gain more of the energy than the less frequent lower frequency modes. 
 

Max Plank’s new formula was able to predict the experimental results IF the frequency which is proportional to the Energy ONLY existed in discreet bundles and was not continuous! That is matter in the black bodies could not vibrate at any frequency and absorb ANY amount of energy. They could only absorb certain energy amounts AND only start vibrating or oscillating at certain frequencies!
 
Max Plank started the quantum revolution!
 
                                                                                 E (energy) =     h     *         f
                                                                        Energy                 =  Planks   *    frequency
                                                                                                                                           Constant
 
    Planks Constant represents a proportionality constant (price per seat!) or the  smallest divisible                                         value that frequency (can have). 
 
                                       It represents the “energy chunk” = 6.63 x 10-34 J s (Joule seconds)
 
                                      Energy is absorbed in chunks of this small value x the frequency of the oscillator.
 
                                                                The oscillator of course are the atoms!!!

 Timeline activity – from 00:00 – 27:35 only this weekend!
 
   Please make a timeline of important events that lead to the 
   development of quantum mechanics (our current model of the atom).
   
Time line activity – Trace the important moments in the development of the atom.
Scientists – dates – places – accomplishments – anecdotes – 
This will be collected once it is completed and YOU ARE ONLY STARTING it!
 
I am asking that you start your timeline from 00:00 to 27:35 of the Clash of the TITANS movie below.
 
I will be collecting this once we complete the entire timeline next week!
 
I have an example posted below which you should model the rest of your Timeline from.
