1. The problem statement, all variables and given/known data Thought Project 7 Skill Level III Problem Laser, which use light rays of set wavelengths (colors), are in constant use in our world, in everything from surgery to supermarket checkout scanners. Execute the necessary research to determine whether the color of a laser affects the velocity of the light wave projected by the laser. Remember to cite the sources you used. 2. Relevant equations I do not have any equations. There was none give for this problem. But, skill level I and skill level II both us the distance=rate x Time formula. I might assume I will be using a variety of it again. 3. The attempt at a solution I cannot attempt to solve the problem because I do not know the equation or even where to begin. When we did Thought Project 5 Colors I use this pdf file to help on a skill level problem and I not sure if it help on this problem and it does have some equation that I not sure if is the one I need. http://www.physics.uc.edu/~sitko/ReflectanceSpectroscopy.pdf" I post help in the wrong area my second night on this forum. And now it will be too late for anyone to help. My assignment in due Monday night. August 2, 2011 I now it is against the rules but I need help more than a normal person for I suffer from a Written Expression Learning Disability.
