Snow affects sound Freshly fallen snow absorbs sound waves, giving everything a seemingly hushed, quieter ambience after a flurry. But if the snow then melts and refreezes, the ice can reflect sound waves making sound travel further and clearer. There are hundreds of words for it It’s often...
Like you can detect oxygen, carbon dioxide, radio waves and electricity even though you can't see them either. The ozone "hole" is actually an area of ozone thinning in the stratosphere which extends from about 15-50 km (10-30 miles) above the earths surface in the atmosphere, it ...
Ultraviolet rays are waves of light that come from the sun. In this lesson, learn about different types of ultraviolet rays, the characteristics and effects of ultraviolet rays, and ways people can protect themselves from their dangers.
at slightly different points which will cause inaccurate viewed colors. This is correct by using an achromatic lens, which is simply two lenses (one positive lens and one negative lens) fused together , this creates a lens that transmits and focuses the different colored light waves to focus ...
Increased ocean heat content contributes to rising sea levels, coral bleaching, melting glaciers and ice sheets as well as ocean heat waves. The heat stored in the ocean will eventually be released and will contribute to increases in the Earth's surface temperature, according toNOAA. ...
Stony, black, and thorny corals of the Hexacorallia order also have external skeletons and can live in shallow tidal areas or up to 20,000 feet under the waves. Some of these corals are solitary and others make up colonies. Colonial polyps measure from 0.04 inches to 1.2 inches in ...
There is much to learn about the UV, visible, near-infrared and beyond character of the upper atmosphere of Venus, and NASA's DAVINCI mission will carry a new class of "hyperspectral" camera to measure it at very high spectral resolution for the first time from flybys. Why is Venus ...
Scattering Rayleigh scattering accounts for the majority (about 96 percent) of attenuation in optical fiber. Light travels in the core and interacts with the atoms in the glass. The light waves elastically collide with the atoms, and light is scattered as a result. Some scattered light is ...
A 2021 study published by theAmerican Meteorological Societynoted that the area's "mountains produce sharp gradients in clouds and rainfall, which are key to abundant rainbow sightings." Air pollution, pollen, and a large amount of cresting waves also help to put Hawaii at the top of the lis...
Despite his mysterious, evasive nature, Invader is full of pithy quotes about his unique artistic practice. Commenting on his choice of — theSpace Invader— Invader once remarked: ‘As these creatures are made of pixels they are in some sorts ready-made for tile reproduction […] their names...
