IMDB rating: 7.30 Plot: A rare atmospheric phenomenon allows a New York City firefighter to communicate with his son 30 years in the future via short-wave radio. The son uses this opportunity to warn the father of his impending death in a warehouse fire, and manages to save his life. However, what he does not realize is that changing history has triggered a new set of tragic events, including the murder of his mother. The two men must now work together, 30 years apart, to find the murderer before he strikes so that they can change history—again. |

The first ionization energy of cesium is 382 kJ/mol. Calculate the minimum frequency of light…?
The first ionization energy of cesium is 382 kJ/mol. Calculate the minimum frequency of light required to ionize gas phase cesium atoms in their ground electronic state.
The equation you need is:
E = Plank’s constant X frequency
First, divide the ionization energy by avogadro’s number to get the energy required to ionize 1 atom. Then, (making sure your units are all the same), just plug the energy and Planck’s constant into the equation and calculate the frequency.
