Which material would allow light to pass through most clearly?

• A. Glass
• B. Wood
• C. Metal
• D. Carpet

Answer: (A)

Light passes most clearly through materials that are transparent, meaning they let light through with little absorption or scattering. Glass fits this description, so you can usually see right through it. Wood, metal, and carpet are opaque or only allow light to scatter or reflect, so they don’t let light pass through clearly. Because of that, glass provides the clearest passage for light among these options.
