Figure 1.1: Ground-based astronomy is confined to the visible and radio atmospheric windows, wavelength ranges in which the atmosphere is nearly transparent. The radio window is much wider than the visible window when plotted on logarithmic wavelength or frequency scales, so it includes a wide range of astronomical sources and emission mechanisms. Radio astronomers usually measure (and think in terms of) frequencies ν=c/λ instead of wavelengths λ. Thus λ=0.3mm corresponds to ν=1 THz, the highest frequency accessible from the best terrestrial sites. The Earth’s ionosphere reflects radio waves longer than λ～30m (ν～10MHz). Abscissa: Wavelength. Ordinate: Atmospheric transmission. Image Credit: ESA/Hubble (F. Granato).

【机器翻译】图1.1：地面天文学仅限于可见光和射电大气窗口，即大气几乎透明的波长范围。当以对数波长或频率标度绘制时，无线电窗口比可见光窗口宽得多，因此它包括各种天文源和发射机制。射电天文学家通常测量（并考虑）频率ν=c/λ，而不是波长λ。因此，λ=0.3mm对应于ν=1 THz，这是从最佳陆地站点获得的最高频率。地球电离层反射的无线电波长度超过30米（10兆赫）。Abscissa：波长。坐标：大气传输。图片来源：ESA/哈勃（F.Granato）。
