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

To determine the correct order of materials in terms of reflectivity from least to greatest, we need to consider how reflective each material typically is:

1. **Black Asphalt** - This is very dark and absorbs most light, making it the least reflective.
2. **Brown Soil** - This can vary, but generally, it is not very reflective compared to lighter materials.
3. **Beige Sand** - Lighter in color than soil, so it has higher reflectivity.
4. **White Paper** - This is highly reflective due to its light color.

So, the order from least to greatest reflectivity is:

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

Thus, the correct answer is:
**black asphalt, brown soil, beige sand, white paper.**
