The term 'monochromatic' refers specifically to light that is composed of one wavelength and one color. In the context of laser light, this is particularly important because lasers emit light that is very specific and coherent, meaning that it consists of one discrete wavelength. This characteristic allows for precision in applications like laser hair removal, as it targets specific structures in the skin effectively.

The other options provide definitions that do not align with the meaning of 'monochromatic.' For instance, light composed of multiple wavelengths would imply a mix, contradicting the idea of being monochromatic. Similarly, light that changes color over time suggests variability, which is not characteristic of monochromatic light. Finally, a spectrum of visible light refers to a broad range of wavelengths, while monochromatic light remains confined to a single wavelength.
