Answer: Between 400 nm and 700 nm
Notes: The human eye is capable of detecting light in the range of approximately 400 nm to 700 nm on the electromagnetic spectrum. This corresponds to the frequency range of about 4 × 10^14 to 7 × 10^14 Hz. This detection range falls within the visible light spectrum. It's fascinating how our eyes are naturally tuned to this specific range, enabling us to perceive the palette of colors in our surroundings but unable to see ultraviolet or infrared radiation that are just outside this narrow band.
