Journal: List the 7 EM waves in order of highest energy to lowest energy.

 

 

 

·       *Energy is proportional to its frequency. The higher the frequency (f), the greater the energy

·       Energy of a photon: E =  hf   =  hc/l

     

 

 

 

Which color of light has the most energy?

R O Y G B I V

 

 

 

  

 

 

n    Energy Levels: Each photon comes from a single jump of an electron from a higher energy level to a lower energy level(s).

 

------------------------------------               n= W     E = 0.0 eV

           n= 4     E = - 0.9 eV

 

     n= 3     E = - 1.5 eV             

    n= 2    E = - 3.4 eV

 

 


 

       E = -13.6 eV                                    ground state    n=1   

 

 

 

               

Example I :  a. How many possible photons may be emitted from this series (n=4)?

      b. Which is the longest wavelength and the shortest wavelength?

      C. How much energy does each have?

 

Answer:

a. 6

b. Longest:   n4 to n3

   Shortest:  n4 to n1  

 

c. 0.6  & 12.7
