This specific wavelength range, roughly between 365nm and 400nm, is what excites electrons in fluorescent substances, causing them to release photons of visible light in vibrant colors. Art restoration experts employ UV light to detect forgeries and assess the condition of old paintings.
Understanding Eye Safety with Black Light and UV Light
