Wave Math – Light

• c = Lf (color = different wavelength & different frequency)
• E = hf (energy proportional to frequency)
• E = hc/L

Bohr – Energy Levels of Hydrogen

• E_n = -2.178 x 10^-18 J (1/n²)
• can calculate the energy of every electron in hydrogen
• practice

Spectrum Activity

• handout in Schoology (H Spectrum)
• in LNB, calculate and then draw
• NOTE: don’t worry about lab sections – just show work
