1.An arrangement of electromagnetic radiation by frequency and wavelength. As a whole, the electromagnetic spectrum ranges from radio waves to gamma rays. The visible spectrum is a band of colors seen when white light is broken up according to wavelengths, as when passing through a prism or str...
有变体名词 In physics, the frequency of a sound wave or a radio wave is the number of times it vibrates within a specified period of time. (物理学) 频率 You can't hear waves of such a high frequency. 你听不到这么高频率的声波。 ...a frequency of 24 kilohertz. …24千赫的频率。 英...
The present invention relates to an array for the propagation of frequency waves ranging from 1 ghz to 10 thz. according to the invention, said assembly comprises: (a) a waveguide (11, 21) for guiding said waves, said waveguide (11, 21) being made of a plastic material, a part of ...
There are a huge range of different sources of waves you can use for example frequency and period calculations, and the more you work for, the more you'll get a feel for the frequency range of different sources. Visible light is really electromagnetic radiation, and travels as a wave acros...
We suggest that high resolution data will show enhanced power in the 0.5 Hz range.关键词: Theoretical or Mathematical, Experimental/ astrophysical plasma plasma electrostatic waves solar activity solar corona/ coronal mass ejections CMEs electromagnetic ion cyclotron waves EICW Wind data AD 1996 08 ...
The generation mechanism of these electrostatic waves is still under investigation, but the observations may imply that these waves reduce the intensity of the heat flux through enhanced wave particle scattering associated with a heat flux instability. 展开 ...
Frequency, the number of waves that pass a fixed point in unit time; also, the number of cycles undergone during one unit of time by a body in periodic motion. A body in periodic motion is said to have undergone one cycle after passing through a series o
Plane waves A discussion of sound waves and their propagation can begin with an examination of a plane wave of a single frequency passing through the air. A plane wave is a wave that propagates through space as a plane, rather than as a sphere of increasing radius. As such, it is not...
