Question

Quizplus · Accepted Answer

The phosphor layer is responsible for emitting light when energized by x-rays. X-rays penetrate the protective coating and base layer, then cause the phosphor to emit light, which in turn exposes the film. The reflective and supercoating layers do not play a role in emitting light when energized by x-rays.
