What is the scientific term for visible electromagnetic radiation?

The scientific term for visible electromagnetic radiation is light. Visible light is the portion of the electromagnetic spectrum that is detectable by the human eye, ranging from wavelengths of approximately 380 to 750 nanometers. This form of electromagnetic radiation is characterized by its ability to produce the sensation of sight when it interacts with the photoreceptors in the retina.

Heat refers to thermal energy, which is not the same as visible light. Ultraviolet and infrared are types of electromagnetic radiation that fall outside the visible spectrum; ultraviolet radiation has shorter wavelengths than visible light, while infrared has longer wavelengths. These forms of radiation are crucial in various applications but do not fall under the category of visible electromagnetic radiation, which is specifically known as light.
