G) all of the above
What information should you record in your notebook?
B) Quench the fire with your wash bottle
and continue with the same applicator.
What should you do if the tip of your applicator catches on
1. (2 pts) For the Balmer series for the hydrogen atom
a. (1 pt) List ni and nf for the four lowest energy levels.
Tol Pts 1
b. (0.5 pts) What are the ni and nf values for the Balmer line that you expect to have
the lowest energy?
c. (0.5 pts) What are the ni and nf values for the Balmer line that you expect to have
the longest wavelength?
Answer question 2 BEFORE you measure the sparkler spectrum
2. (1 pt) What might cause the wider bands of light you observe in some of the flame
spectra compared to the hydrogen lamp?
3. (6 pts) Two different sparkler spectra have been given to you, each with spectra
taken close up and farther away to help you identify both strong and weak features.
scale peak at high wavelength is centered
at approximately 769 nm. Identify as many lines or bands as you can, based on
comparison with your flame
spectra. Put the names of the metal (Na, Li, K, Sr, Ba, and/or Cu) directly on the
spectra, with an arrow
