What light can humans not see and how does it impact our understanding of the world around us?

Ultraviolet light is a type of light that humans cannot see, but many animals can. This impacts our understanding of the world around us because there are things happening in nature that we cannot perceive without the ability to see ultraviolet light. For example, some flowers have patterns that are only visible in ultraviolet light, which helps attract pollinators. By not being able to see ultraviolet light, we may be missing out on important information about the natural world.
