What is the energy loss in total internal reflection?

7. In total internal reflection light inside a dense medium reflects from the boundary to a less dense medium. Since by Snell''s law there is no allowed refracted ray, all energy continues along the reflected ray. In the wave picture there is an evanescent wave decaying exponentially in the thinner medium but not transmitting any energy outward.
