reflectivity

/ɹᵻflɪktˈɪvᵻɾi/ noun

The ability of a surface to bounce back light or sound.

Word Origin Reflectivity is the quality of bending back, from Latin 'reflectere' 'to bend back,' from 're-' 'back' and 'flectere' 'to bend.' The root 'flectere' gives us flex (bend), flexible (bendable), deflect (bend away), inflect (bend in, change tone), and genuflect (bend the knee). The PIE root '*bhlek-' meant 'to bend.'
