ARoughly 20 to 400 nm
BRoughly 400 to 700 nm
CRoughly 0.01 to 20 nm
DRoughly 700 to 900 nm
Answer & Solution
Correct answer: B. Roughly 400 to 700 nm
1. Human vision responds to only a narrow slice of the whole spectrum.
2. That slice runs from roughly 400 to 700 nanometers.
3. It is also the band that passes most easily through the air, which is no coincidence.
