When can laser light be seen in relation to the light spectrum?

Laser light can be distinctly seen within the visible light spectrum, which corresponds to the range of colors identifiable by the human eye. The color spectrum of the rainbow illustrates the various wavelengths of light that are visible, including reds, greens, blues, and violets. Lasers can emit light in specific colors, such as red, green, and blue, aligning with this spectrum.

The options that refer to the infrared and ultraviolet ranges relate to parts of the electromagnetic spectrum that are not visible to the human eye. Therefore, while lasers can operate in those ranges, the light they emit is not seen by human observers. The choice that describes the color spectrum of the rainbow accurately represents the visible light portion of the electromagnetic spectrum, clarifying that laser light can indeed be seen in this specific context.
