Introduces the science of physics, covering such topics as matter, motion, and magnetism; profiles important physicists including Albert Einstein and Enrico Fermi; and features simple experiments to demonstrate key concepts.In order to make sense of all the light pathways, physics has evolved a technique called the ray diagram. Out of all the many rays that are emitted from any point, only particular ones will be traced. Leta#39;s start with a plane mirror. In ray diagrams anbsp;...
