These equations can be proved by a geometrical argument (Longhurst, 1962) or by setting /^oo and F020 equal to zero (see Eq. Al and Table Al). 4. Geometrical Descriptions of Mirror Surfaces. Another useful way to approximate a mirror surface is to ex
The 19th and early 20th centuries saw great advances in our understanding of the atom. This module takes readers through experiments with cathode ray tubes that led to the discovery of the first subatomic particle: the electron. The module then descr
