12. Oxygen atom emits green light with a wavelength of 780 nm . Calculate the frequency of this light. 13. A FM radio station in Lusaka broadcasts at 99.5 MHz . Calculate the wavelength of the corresponding radio waves. 14. Element $ Y $ emits a blue photon with a wavelength of $ 4.8 \times 10^{-5} \mathrm{~cm} $. Calculate, a) The energy of a blue photon in joules b) The energy of a blue photon in electron volts ( eV ). 15. It takes $ 7.21 \times 10^{-19} \mathrm{~J} $ of energy to remove an electron from a sodium atom. What is the maximum wavelength of light that can do this? 16. A copper bullet has a velocity that is $ 90 \% $ of the speed of light. If the wavelength of the copper bullet is $ 1.5 \times 10^{-3} \mathrm{pm} $, calculate the mass of the copper bullet. 17. Calculate the wavelength of light emitted when the following transition occurs in the hydrogen atom, $ \mathrm{n}=5 $ to $ \mathrm{n}=3 $. 18. An excited hydrogen atom emits light with a wavelength of 397.2 nm to reach the energy level for which $ \mathrm{n}=2 $. In which principal quantum level did the electron begin? 19. An electron in a certain atom is in the $ \mathrm{n}=2 $ quantum level. List the possible values of $ l $ and $ \mathrm{m} / $ that it can have. 20. Using the Heisenberg uncertainty principle, calculate $ \Delta \mathrm{x} $ for an electron with $ \Delta v=0.100 $ $ \mathrm{m} / \mathrm{s} $.

Even though he won't be able to implement his ideas for several months, Brett is learning about introducing food to the girls. He's even ordered a few kitchen gadgets to make homemade baby food. Brenna finds it endearing, but kindly reminds him that they are waiting until the girls are 6 months old to begin introducing foods, if they're developmentally ready at that time, as they were born at 37 weeks. Match the infant age range to the approximate mouth patterns, development skills, and expected eating abilities.
