Nuclear energy is released at the sun’s center as high energy gamma radiation, a form of electromagnetic radiation like light and radio waves, only of very much shorter wavelength.比较结构的理解。本题要求听者分辨清所比较之物及其对比关系。原文谈到Nuclear energy(核能)时,将其解释为high energy gam...
她在哪里将有时间? [translate] aLong-wave radiation energy is a form of heat while short wave radiation energy is visible light from the sun 当短波辐射能量是可见光从太阳时,长挥动辐射能量是热的形式 [translate] 英语翻译 日语翻译 韩语翻译 德语翻译 法语翻译 俄语翻译 阿拉伯语翻译 西班牙语翻译 ...
To a physicist,lightmeans an energy that is anywhere along the electromagnetic spectrum, from ELF waves to gamma radiation. Visible light is only a narrow part of the spectrum that is most familiar to us because our eyes can detect it. In the Newtonian model of the universe everything is m...
light are multiple. Light is an energy source, converted to sugars by photosynthesis. It is also a signal sensed by specific photoreceptors for red, blue and UV-B radiation. Absence of light leads to a developmental program called etiolation. Excess of light constitutes a form of abiotic ...
athe nuclear energy is released at the Sun's center as high-energy gamma radiation, a form of electromagnetic radiation like light and radio waves, only of very much shorter wavelength. This gamma radiation is absorbed by atoms inside the Sun to be reemitted at slightly longer wavelengths. Thi...
A molecular aggregate formed in a two-dimensional organic–inorganic hybrid perovskite superlattice with a near-equilibrium distance is shown to have a near-unity photoluminescence quantum yield like that of single molecules, despite being in an aggregated state. Kang Wang , Zih-Yu Lin & Letian Dou...
Light is a form of electromagnetic wave that consists of oscillating electric and magnetic fields. Figure 5.1 illustrates the wavelength and frequency range of visible and invisible light along with those of other types of electromagnetic waves. The wavelength of visible light ranges from about 400 ...
When an element, in its atomic state, is placed in a flame the atoms increase in energy, become ‘excited’ and emit energy in the form of light in order to attain their original energy state. The light energy emitted is specific in wavelengths for each element, e.g. sodium emits light...
aA giant explosion of magnetic energy from the sun, called a coronal mass ejection, slams into and is deflected completely by the Earth's powerful magnetic field. The sun also continually sends out streams of light and radiation energy. Earth's atmosphere acts like a radiation shield, blocking...
aAccording to the SPS idea, turn light energy into electricity energy – and converted to microwave energy back to Earth – microwave radiation back to the DC at the surface – Finally through invert convert ways and so on conversion into industrial AC electrical power. 根据SPS想法,把光能变成电...
