Light and the Electron Test Review Waves 1. Label the letters on the wave pictured to the right. 2. Order the waves below from lowest frequency to highest frequency (Hint-some may be equal). Wave and Light Equations What is the speed of light equal to? What is Planck’s Constant equal to? 1. What is the wavelength of light that has a frequency of 4.22 x 1015 Hz? 2. What is the energy of light that has a frequency of 1.30 x 1014 Hz? 3. What is the frequency of a wave of light with the wavelength of 450 nm. 4. 0.825 M = _______ nm 5. The wavelength of a certain beam of light was 3.52x10-7m. a) Find the frequency of this light. b) Calculate how much energy this light has. Light Emissions The diagram to the right shows 4 possible electron emissions. Use the diagram to answer the following questions. 1. Is energy being absorbed or released in the diagram? How do you know? 2. There are four wavelengths present in the diagram: violet, blue, green, and red. Which atom represents each color? 3.
