UV Rays
UV rays are the invisible electromagnetic waves with wavelengths shorter than visible light but longer than X-rays, primarily emitted by the sun and certain artificial sources. They play a crucial role in natural processes like vitamin D synthesis in human skin and DNA damage that can lead to mutations. In today's world, UV rays are both a health hazard, linked to skin cancer, and a tool in technologies like water purification.
Did you know?
Bees and other insects can see UV rays, revealing hidden patterns on flowers that guide them to nectar, a phenomenon estimated to influence pollination in over 75% of the world's flowering plants. This UV vision has evolved for at least 100 million years, giving pollinators an edge that humans lack without special equipment.
