ABSTRACT
At the beginning of the twentieth century, two great revolutions in physics occurred that changed the way physicists viewed the world. One is known as quantum mechanics and the other is Einstein’s theory of relativity. Interestingly, they both were initially concerned with the nature of light. Quantum mechanics began with an attempt to understand how light interacted with matter, while an integral part of relativity has to do with the speed of light. Therefore, it is tting that before we discuss these two great theories, we take some time to discuss light and its properties.
