Which term refers to the range of light visible to the human eye?

Explanation:
The range of light visible to the human eye is called the visible spectrum. Light exists across a broad electromagnetic spectrum, but our eyes respond only to a narrow band of wavelengths roughly from about 400 nanometers (violet) to about 700 nanometers (red). Within this band we see colors. Ultraviolet lies beyond the violet end and isn’t visible. An opaque object blocks light, and a filter transmits some wavelengths while blocking others, but neither defines the range of light we can see.
