Here's why:
* Visible light spectrum: The human eye can only see light within a specific wavelength range, roughly 380 to 750 nanometers. This range corresponds to the colors we see in a rainbow, from violet (shortest wavelength) to red (longest wavelength).
* Ultraviolet light: 300 nanometers falls within the ultraviolet (UV) range of the electromagnetic spectrum. UV light is invisible to the human eye.
While we can't see 300 nanometer light directly, it can still have effects. UV light can cause sunburn and damage our eyes. That's why it's important to wear sunscreen and protective eyewear when exposed to strong UV radiation.
