It is true since the energy of a light wave is inversely proportional to its wavelength.Give the right answers plss don't answer blank just for points!ġ.) If the light has a longer wavelength, it has a lower energy. As a wave, light is part of the electromagnetic waves as the visible spectrum or white light. These can be observed in different phenomena such as rainbows, red sunset, and blue sky.ġ5. Brightness or intensity and colors are special properties of light.
Dispersion is a phenomenon in which a prism separates white light into its component colors.ġ4. As the frequency of light decreases, the wavelength becomes longer.ġ3. As the frequency of light increases, the wavelength becomes shorter.ġ2. As the wavelength of light becomes longer, the energy increases.ġ1. As the frequency of light increases, the energy also increases.ġ0. White light consists of different colors.ĩ. The color red has the lowest energy and frequency.Ĩ.
The shorter the wavelength, the lower the energy.ħ. The color red has the highest energy and frequency.Ħ. The color violet has the highest energy and frequency.ĥ. Red from the color spectrum has the longest wavelength.Ĥ. Light with a shorter wavelength has a higher energy.ģ. If the light has a longer wavelength, it has a lower energy.Ģ. And last year, an Italian locksmith captured the first ever shot of a supernova's first light.Direction: Write TRUE if the statement is correct, and FALSE if it is otherwise.ġ. In 2013, dashcams proved to be crucial to understanding a small asteroid that struck Russia. STEVEs are far from the only important scientific finds that have been made on commercial devices. “As commercial cameras become more sensitive and increased excitement about the aurora spreads via social media, citizen scientists can act as a ‘mobile sensor network,’ and we are grateful to them for giving us data to analyze,” says Toshi Nishimura, a space physicist at Boston University and lead author of the new study, in the release. Learning about them has been an effort showcasing the strength of amateur-professional scientific alliances. Scientists completely missed STEVEs until amateurs brought the odd lights to their attention. “The precipitating electrons that cause the green picket fence are thus aurora, though this occurs outside the auroral zone, so it’s indeed unique.” What's the distinction? “Aurora is defined by particle precipitation, electrons and protons actually falling into our atmosphere, whereas the STEVE atmospheric glow comes from heating without particle precipitation,” says Bea Gallardo-Lacourt, a space physicist at the University of Calgary and coauthor of the new study, in the release.
It's a process similar to what causes auroras, but in a different location. High-frequency waves can knock out of the magnetosphere to the ionosphere, which creates the green picket fences. While the river of charged particles is colliding in the ionosphere, in the magnetosphere, energetic electrons are streaming around Earth. Incandescent light bulbs work in much the same way, where electricity heats a filament of tungsten until it’s hot enough to glow.īut STEVEs contain multitudes. Here's what probably happens during a STEVE, according to the press release: A flowing “river” of charged particles in Earth’s ionosphere collide, creating friction that heats the particles and causes them to emit mauve light. So scientists analyzed data from satellite footage of STEVE events between April 2008 and May 2016 to measure electric and magnetic fields in the magnetosphere.Īfter matching the data with amateur photos, the scientists-an international team from the U.S. The ionosphere overlaps with Earth’s magnetosphere, the area of space surrounding our planet that's controlled by its magnetic field. Their best guess was that a STEVE originated in the ionosphere, an upper part of the Earth's atmosphere. Play icon The triangle icon that indicates to play
