In the transfer matrix method, a simple form of this process is represented by an identity matrix. In AC power lines, the scaled difference between load and characteristic impedance is a coefficient named for this process symbolized capital gamma. This process lends its name to the fraction of particles that do not tunnel through a barrier. (0[1])This process is effectively blocked by a (*) thin film if the path length is half this (0[1])process’s phase (10[1])shift. (0[1])The fractions of this process and transmission sum to one. (0[1])The angle of incidence (10[1]0[1])equals (10[1]0[1])the angle (10[1])of (10[1])this (10[2])process (0[4])on a (10[1])flat surface. (10[4]0[1])Optical signals (10[2])are stuck (10[1])inside a waveguide by the “total internal” (10[1])form (10[5])of this (10[1])process. (10[3]0[2])For 10 points, name this process by which light bounces off mirrors. (10[4])■END■ (10[6])
