Name: ____________________________________      Period: _____________________

Using your understanding of these labs and information in your lab notebook, answer the following questions in the space provided.

1.   When you exposed copper (as an ion in solution) to a flame, what color did you see? _______________________.

2.   In either the Flame Test Lab and/or Bright Line Demo, what is the piece of equipment you used to better detect wavelength/frequency/energy of light? ____________________________

3.   From your calculations and/or knowledge of Light/energy/combined equations, how are Energy (E) and Wavelength (λ) related?
a.  Directly
b.  Indirectly ( I call it Inversely)
c.  Is the same numeric value but different units
d.  Need more information to answer question

4.   Why is the Bright Line Spectrum unique to each element?
a.  It represent the mass of the element /atom (and all elements have different masses)
b.  It represents the volume of element/atom (with more lines indicating a larger volume)
c.  It represents the movement of electrons in the element/atom (with each element having a different number of lines/electrons moving)
d.  It is not unique to each element.

5.   In the Flame Test lab, you exposed an ion/atom to a flame (energy) and "saw" a color. Explain what is happening in the atom to produce the color.






6.   On the bottom of the back of this page, write the 2 conclusions you made in this lab. If you reference to Bright line spectrum from your lab data, describe them in your answer using the following method, 2 red line, 1 green and 4 blues.

7.   On the top of the back of this page, choose one of your color (used a specific wavelength in nm instead of color) to Energy calculations and rewrite all appropriate work (including units).
DO NOT SHOW THE FREQUENCY CALCULATIONS, JUST THE ENERGY CALCULATIONS.
