Ultraviolet rays are waves of light that come from the sun. In this lesson, learn about different types of ultraviolet rays, the characteristics...
Seven of them were successful, and analyzed the sun at ultraviolet and X-ray wavelengths and photographed the super-hot corona, among other achievements. In 1990, NASA and the European Space Agency launched the Ulysses probe to make the first observations of its polar regions. In 2004, NASA'...
Venus' surface is extremely dry. During the planet's evolution, ultraviolet rays from the sun evaporated water quickly, keeping Venus in aprolonged molten state. There is no liquid water on its surface today because the scorching heat created by its ozone-filled atmosphere would cause water to ...
Australia's ARPANSA has published a news story, on March 17, 2021, about both reviews and… boasted that the reviews are "World-first reviews into 5G radio waves". There is no doubt that in science being "the first" is important. Any scientist interviewed by a journalist gets a question...
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 ...
Some animals have sense receptors that we cannot even dream of… Snakes, not all of them, have sensory organs, which can detect infrared light. While most bees and birds can see ultraviolet light. We also have dolphins and bats that use sonar sounds to interpret and communicate. Then, there...
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...
are not that different from any other type of light, whether incandescent, fluorescent, or just the age old candle flame. The difference is that black lights emit most of their light waves just outside the range humans can perceive, in the Ultraviolet (UV) part of the spectrum. When […...
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-...
they can only be seen in ultraviolet light. Uranus and Neptune also display their own auroras, but little is known about their origin and nature, comparatively. But the auroras on Uranus prove that the lights are beautiful anywhere in the solar system, appearing as thin streaks of bright white...
