Final answer:
Light with a wavelength of 500nm falls within the C. visible spectrum, and is associated with the color green. This places it outside of the ultraviolet and infrared ranges.
Step-by-step explanation:
Light with a wavelength of 500nm contributes to the visible spectrum. The visible spectrum ranges approximately from 380nm to 740nm, where each wavelength corresponds to a different color perceivable by the human eye. Within this range, 500nm is associated with the color green, which is towards the middle of the visible spectrum. This wavelength is longer than ultraviolet (UV) light and shorter than infrared (IR) light, excluding it from contributing to either of those passbands.
Therefore, the correct answer to the question is C) Visible. The divisions between infrared, visible, and ultraviolet are not perfectly distinct, but the wavelength of 500nm clearly falls within the visible range of the electromagnetic spectrum.
