The visible spectrum refers to the range of wavelengths of electromagnetic radiation that can be detected by the human eye. It includes wavelengths of light that produce the sensation of different colors, ranging from violet (with a wavelength of about 400 nanometers) to red (with a wavelength of about 700 nanometers). Therefore, the best choice is D, electromagnetic radiation.
