What makes paper opaque?

Mar 7, 2018

Paper consists of fibers with air spaces between them. When light passes through paper it hits the fibers, which scatters the light by changing the light's direction. The more the light is scattered the more opaque the paper. This light scattering is referred to as internal reflection. Filler also increases the opacity.
