Question

Which is the correct order of materials in terms of reflectivity, from least to greatest?

brown soil, beige sand, white paper, black asphalt
white paper, beige sand, brown soil, black asphalt
black asphalt, brown soil, beige sand, white paper
beige sand, white paper, black asphalt, brown soil

Answer 1

black asphalt, brown soil, beige sand, white paper

Explanation: darker surfaces absorb more light (lower reflectivity). Asphalt is very dark (lowest), brown soil is intermediate, beige sand is lighter (higher reflectivity), and white paper reflects the most.
