[漢羅] 太陽 kah 伊 phàng-kìⁿ ê 色光

遮有 太陽 所有 看會著 ê 色光，是日光迵過 像 稜鏡 這款家私 ê 時陣產生--ê。 這个 光譜 是 McMath-Pierce 太陽天文台 做--ê。 先講一下，咱 白色 ê 太陽 其實會發出 全部 ê 色光，毋過伊 tī 黃色 kah 青色 是 上光--ê。 這張光譜 內底一逝一逝較暗 ê 部份，是 太陽表面 抑是 頂懸 ê 氣體 吸收 下底 leh 發射 ê 日光。 無仝氣體會 吸收無仝色光，這會當幫贊咱了解太陽 ê 組成氣體是啥物。 舉一个例，日素 就是 1870 年 先 tī 太陽光譜內底揣著，後來 才 tī 地球 揣著 ê 元素。 今仔日咱已經有法度知影大部份 ê 光譜吸收線 是 ùi 佗一个元素來--ê，毋過 猶有一寡毋知。

[English] The Sun and Its Missing Colors

Here are all the visible colors of the Sun, produced by passing the Sun's light through a prism-like device. The spectrum was created at the McMath-Pierce Solar Observatory and shows, first off, that although our white-appearing Sun emits light of nearly every color, it appears brightest in yellow-green light. The dark patches in the featured spectrum arise from gas at or above the Sun's surface absorbing sunlight emitted below. Since different types of gas absorb different colors of light, it is possible to determine what gasses compose the Sun. Helium, for example, was first discovered in 1870 on a solar spectrum and only later found here on Earth. Today, the majority of spectral absorption lines have been identified - but not all.
