Why bees can see objects placed in ultraviolet light whereas we as humans cannot
Answers
Like infrared light, ultraviolet light is visible to some animals. Bees and other insects can see higher frequencies than people can. They see nectar guides—marks that show where nectar is located—that people cannot see with visible light. The photographs below show how one flower might look to a person and to a bee.
The human eye cannot process ultraviolet light waves because they have shorter wavelength than violet. Human eyes can see only between 380 nm (violet light) and 750 nm (red light).
Bees can see ultraviolet light because their vision differs from humans. Ultraviolet light receptors have been found in analysis of diurnal birds, having been found over 40 species using a combination of microspectrophometry, electrophysiology, behavorial methods and gene sequencing.
