Inverse Square Law for Radiation: Definition & Formula

WebGraham's law of effusion (also called Graham's law of diffusion) was formulated by Scottish physical chemist Thomas Graham in 1848. Graham found experimentally that the rate of effusion of a gas is inversely proportional to the square root of the molar mass of its particles. This formula is stated as: =, where: Rate 1 is the rate of effusion for the first gas.
