Flame Test Experiment
The numbers above the spectral lines
represent their wavelengths (λ)
The wavelengths are measured in 100 nm (i.e. the middle green line has a λ of 550nm)
Flame Test Experiment

Lab station needs to be cleared off
Clean Up Stamp needs to be
received before you leave: worth 5
LOTS of Calculations. Here are the
formulas and constants
= c / λ E = h = frequency c = speed of light (3.0 x 108 m/s)
λ = wavelength (in m)
E = energy (in J)
What would the other wavelengths be in m?

How to draw the Electron Jumps
A part of your Post-Lab includes drawing a
Bohr atom showing possible the electron
jumps for the observed spectral lines.
