Cracked glass appears shiny
Cracked glass appears shiny due to reflection. When light encounters the cracked surface, it reflects off the irregularities, creating a shiny appearance. This reflection occurs because the smooth surfaces of the cracks act as mirrors, bouncing light back towards the observer.

Cracked glass appears shiny primarily due to reflection (Option B). When light hits the irregular surfaces of the cracks, it reflects off these surfaces like mirrors, creating a shiny appearance. This phenomenon is distinct from refraction (Option A), interference (Option C), or total internal reflection (Option D), which involve different interactions of light with materials. The shiny appearance of cracked glass highlights how light behaves differently when encountering irregular surfaces compared to smooth ones, showcasing the role of reflection in perception and aesthetics.
