The wavelength range for visible light is from 400 to 700 nanometers. This range corresponds to the portion of the electromagnetic spectrum that can be detected by the human eye, allowing us to perceive different colors. The shorter wavelengths within this range (approximately 400-490 nanometers) correspond to blue and violet light, while the longer wavelengths (approximately 620-700 nanometers) correspond to red and orange light.

The other ranges mentioned in the other choices do not fit the definition of visible light. Wavelengths from 10 to 400 nanometers represent ultraviolet light and possibly some near-infrared light at the lower end. Wavelengths from 700 to 800 nanometers and 800 to 1000 nanometers fall into the infrared region, which is invisible to the human eye. Thus, the range of 400 to 700 nanometers is definitive for visible light, making it the accurate choice.
