Ultraviolet rays are waves of light that come from the sun. In this lesson, learn about different types of ultraviolet rays, the characteristics...
The human eye has the capability to see visible light, while bees also have the capability to see ultraviolet rays, which come out of the sun. Mo... Learn more about this topic: Electromagnetic Waves | Uses & Examples from Chapter 19/ Lesson 2 ...
Optical Physics Facts The energy of light is measured in waves on the electromagnetic spectrum. Invisible lights like ultraviolet and X-rays have shorter wavelengths than visible light. A refractive index indicates how much light will slow down traveling through a medium like glass or water. Ordinar...
Because of pollution, the Earth's ozone layer has suffered a lot. That's bad news for everyone, since the fragile gas layer protects our planet and shields us from the sun's harmful ultraviolet rays. Fortunately, climate change experts believe that the ozone layer will recover to '80s statu...
Some Facts About Light Light is made of electromagnetic radiation and always follows a straight path. Visible light is the type of light that humans can see, but there are also other types of light that we can't see, such as ultraviolet and infrared light. Our human eyes are not able ...
15. Elephants use mud as sunscreen to protect their sensitive skin from ultraviolet light. While it’s skin is 2.5cm (1 inch) thick and generally tough, it’s extremely sensitive, and requires protection from the sun and insect bites. ...
This allows them to see ultraviolet, visible and polarized light. 8. Mantis Shrimp Are Older Than the Dinosaurs Biologists believe stomatopods split from other crustaceans and began evolving separately around 400 million years ago. Meanwhile, dinosaurs didn't turn up for around another 170 ...
Venus' surface is extremely dry. During the planet's evolution, ultraviolet rays from the sun evaporated water quickly, keeping Venus in a prolonged molten state. There is no liquid water on its surface today because the scorching heat created by its ozone-filled atmosphere would cause water t...
and it’s gravitational pull is responsible for our orbit and therefore day and night, on the other hand human skin is sensitive to extreme temperatures and ultraviolet light, which is the cause of hundreds of deaths during heat-waves as well as harmful skin conditions (not to mention it can...
It’s a combination of two distinct pigments: one red (hipposudoric acid) and one orange (norhipposudoric acid). These pigments absorb ultraviolet light, preventing damaging rays from penetrating the hippo’s skin. Moreover, this secretion is both antibacterial and antifungal, providing an all-...
