enounce, enunciate, pronounce, sound out, articulate, say - speak, pronounce, or utter in a certain way; "She pronounces French words in a funny way"; "I cannot say `zip wire'"; "Can the child sound out this complicated word?" ...
The formula is simple: E = h f, or in words: the photon energy (E) is a fixed number by the name of the Planck constant (h, about 4.14 electronvolt per hertz) times the frequency (f). 5. Maybe someone should come up with special anti-radiation products to protect us from ...
We shall also suppose that the radiation does not pass through the body; in other words, all radiation not reflected is completely absorbed. Then the quantity of radiation (63.20) must be balanced by the radiation emitted by the body itself in the same directions at the same frequencies. ...
Gray objects have a uniform ability to absorb all parts of the electromagnetic spectrum. Colored objects behave in similar but more complex ways, which gives them a particular color in the visible range and may make them special in other ranges of the nonvisible spectrum. Take, for example, t...
In a simple fluid, such as carbon tetrachloride, inelastic collisions can produce an increase in the population of the various vibrational and rotational states possessed by the molecule. At low frequency or long times, the sound wave can efficiently perturb the population of states feeding energy ...
athe simplest scheme in which one can test the entangling capabilities of radiation pressure is a simple linear Fabry-Perot cavity with two vibrating mirrors (see Fig. 1) 你可能测试辐射压力的卷入能力的最简单的计划是一个简单的线性Fabry-Perot洞用二个振动的镜子(看见。 1)[translate]...
Gravitational waves transmit energy as gravitational radiation, which is a kind of radiant energy similar to electromagnetic radiation. In other words, gravitational radiation is to gravity what light is to electromagnetism. Theorized by Albert Einstein in 1916, gravitational waves are ripples in the ge...
1(b). In simple words, the proposed non-contact illusion device (Fig. 1(b)) makes the radiation pattern of Fig. 1(a) exactly the same as of Fig. 1(c). Figure 1 The working phenomenon of the non-contact illusion device that distantly delocalizes the emission of antenna into a ...
]. Some reports mentioned the disruption of two measures of semantic memory, namely the postencoding retrieval from long-term memory of words auditorily presented and recognition of a large set of nameable pictures, indicating an impairment of higher perception and memory in auditory and visual ...
It can be spread in a vacuum and air; 3. Accompanying the change of energy form; 4. It has strong directivity; 5. Radiant energy is related to temperature and wavelength; 6. The emitted radiation depends on the fourth power of the temperature. At present, in heat radiation-related researc...
