During X-ray film development, light or X-ray exposure causes the ______ in the emulsion to develop an invisible latent image.

Explanation:
Grains. The emulsion is made of silver halide grains suspended in gelatin. When the film is exposed, energy creates latent image centers inside those grains, which is invisible to the eye. During development, the developer reduces the exposed silver halide in those grains to metallic silver, making the latent image visible as the radiographic image. The gelatin binder simply holds the grains in place, and the crystal lattice is a property of the grains themselves but isn’t where the latent image sits.
