This worksheet has 10 questions. It includes 3 questions on calculating the energy of electron transitions. The next 4 questions require students to calculate wavelength and frequency (using E=hv and C=λv) from these energies. The final few questions tie visible light wavelengths to these electron transitions and ask students to calculate the energy of each color. Use it to provide students with practice problems after going over notes in class. The best part is that you can bring sig figs back into the discussion!
This product comes in WORD format, so it's fully editable. It also includes an answer key!
