As
its name suggests, UV light is beyond the violet end of the spectrum,
and is invisible to humans. However, photographic film is sensitive
to UV light. UV light can be used in medical diagnosis for some skin
conditions, and can be used as a forensic tool to detect forgery of
art or documents. Flowers photographed in UV light often reveal patterns
on the petals which only insects, with their UV-sensitive eyes, can
see. Fluorescent dyes, which glow under UV light, may be used as markers
to make cells more visible, or may be used to highlight otherwise invisible
stress fractures in metal components.
