There is no evidence to suggest that Nikola Tesla had the ability to visually see a larger section of the electromagnetic spectrum compared to typical humans. While Tesla was a brilliant inventor and electrical engineer known for his contributions to alternating current (AC) power systems, wireless transmission of energy, and other technologies, there is no documented indication that he possessed any extraordinary visual abilities or perception beyond the normal range of human vision.
The visible spectrum is the range of electromagnetic radiation that can be detected by the human eye, spanning from approximately 400 to 700 nanometers, corresponding to the colors from violet to red. This range is consistent across the general human population, and individuals typically perceive light within this range similarly.
Perceiving electromagnetic radiation outside the visible spectrum, such as ultraviolet (UV) or infrared (IR) light, would require specialized equipment or devices that can convert these wavelengths into visible light or provide other means of detection. While Tesla conducted extensive research in the field of electricity and electromagnetism, there is no specific evidence to suggest that he had the ability to see or perceive wavelengths beyond the normal human visual range.
It's worth noting that some individuals may have certain genetic conditions or acquired abilities that enable them to perceive slightly different aspects of the electromagnetic spectrum, such as a slightly extended range into the ultraviolet or infrared regions. However, there is no information to suggest that Tesla possessed such abilities.
Therefore, based on available knowledge and historical records, it is reasonable to conclude that Tesla's visual perception was within the normal range of human vision and did not extend beyond the visible spectrum.
