Question

which of the following electromagnetic wavelengths do not stimulate color vision in humans? a. 0.4 - 0.5 μm b. 0.6 - 0.7 μm c. 0.3 - 0.4 μm d. 0.5 - 0.6 μm

Explanation:

The visible - light spectrum for human color vision ranges approximately from 0.4 - 0.7 μm. Wavelengths outside this range do not stimulate color vision. Option c (0.3 - 0.4 μm) is in the ultraviolet range which is outside the visible - light spectrum for humans.

Answer:

C. 0.3 - 0.4 μm
