WebSep 12, 2024 · A clue to the physical meaning of the wavefunction Ψ(x, t) is provided by the two-slit interference of monochromatic light (Figure 7.2.1) that behave as electromagnetic waves. The wavefunction of a light wave is given by E ( x, t ), and its energy density is given by E 2, where E is the electric field strength. WebThe absorption coefficient for a wave is defined as γ = Q ¯ / 2 q ¯ where Q ¯ is the (time) average energy dissipated per unit time and volume, and q ¯ is the mean energy flux density in the wave.
