English-Chinese/Electromagnetic spectrum

The Electromagnetic (EM) Spectrum is the range of all possible electromagnetic radiation. Electromagnetic radiation can be divided into octaves — as sound waves are — adding up to eighty-one octaves. Physicists have studied electromagnetic radiation with wavelengths from thousands of kilometers down to fractions of the size of an atom. It is commonly said that EM waves beyond these limits are uncommon, although this is not known to be true. The short wavelength limit is likely to be the Planck length, and the long wavelength limit is the size of the universe itself, though in principle the spectrum is infinite.

电磁频谱 是 所有 可能的 电磁辐射的 范围。电磁辐射 可以 分为 八度 - 就像 声波 一样 - 加起来 达 八十一个 八度。物理学家 研究了 波长 从 数千 千米 到 原子 大小的 电磁辐射。人们 普遍 认为，超出 这些 极限的 电磁波 并不常见，尽管 事实 并非如此。短波长 极限 可能 是 Planck长度，长波长 极限 是 宇宙 本身的 大小，但 原则上 频谱 是 无限的。
