1. How is the energy of the electromagnetic wave divided between the parts of the wave?
2. What are the range of frequencies and wavelengths of the visible part of the spectrum?
3.What is the relationship between the ray showing the direction of motion the wave moves and the wave front of the wave?
4. If a second polarizer has its transmission axis perpendicular to the first polarizer, what is the intensity of the light that exits the second polarizer?
5. If a third polarizer is placed between the first two but its transmission axis is not lined up with either transmission axis, will the intensity of the light that exits the last polarizer be the same as the previous question? Why or why not?
