Analysis: The electromagnetic spectrum is shown below. Recall that energy is proportional to frequency, while frequency is inversely proportional to wavelength. Use this information to answer questions 1-4 below. Wavelength Radi 30 Frequency THE ELECTROMAGNETIC SPECTRUM tola U Kay Gamma Ray wwwwwwww 1. What is the relationship between energy, frequency, and wavelength? 2. List the colors observed in this lab from the shortest wavelength to the longest wavelength. 3. Based on the results of your experiment, what metal was found in the unknowns "A" and "D" from the video? Explain.
4. How are electrons "excited" in this part of the experiment? What does it mean when the electrons are "excited"? 5. Why do you think the chemicals have to be heated in the flame first before the colored light is emitted?
