In terms of optical density, what impact does a denser material have on light?

• A. It transmits light more effectively
• B. It decreases light transmission
• C. It reflects more light
• D. It does not change light transmission

Answer: (B)

A denser material has a higher optical density, which indicates that it is less transparent and typically absorbs more light. Consequently, as the optical density increases, light transmission through the material decreases. This is because the denser the material, the more interactions the light has with the particles in the medium, leading to more scattering and absorption. In optical terms, materials with higher optical density are more likely to impede the passage of light, thus reducing the amount of light that can successfully transmit through them. Examples of dense materials include glass and certain plastics, which may appear clear but still have significant optical density compared to air or vacuum, leading to reduced light transmission.
