255nm vs 365nm UV Light on Yooperlites | Surprising Results

When white light, such as sunlight, interacts with a dispersive medium like a prism, it separates into its constituent wavelengths due to the varying degrees of refraction for different colors. 🟣 Violet: 380–450 nm (nanometers) 🔵 Blue: 450–495 nm 🟢 Green: 495–570 nm 🟡 Yellow: 570–590 nm 🟠 Orange: 590–620 nm 🔴 Red: 620–750 nm This range of wavelengths constitutes the visible spectrum, which is the portion of the electromagnetic spectrum that human eyes can detect. Each color corresponds to
