An electron in a piece of aluminum requires at least 6.73e-19 J of energy to be ejected from the aluminum. What wavelength of EM radiation does this correspond to? If instead the electron in Problem #6 is struck by EM radiation with a wavelength of 205 nm, how much kinetic energy will it have upon leaving the aluminum? What is the final speed of the electron in Problem #7?

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
