<br/>Q:為什麼日間的天空是藍色,傍晚時是橙紅色? <br/><br/>A:因為多色的陽光被大氣層的分子和懸游粒子散射,而人眼見到的散射效果又隨太陽的高度改變。<br/>晚霞較黎明的霞光更偏紅,因為日間的熱氣流上升使大氣層含更多懸浮粒子將陽光散射,到黎明時,氣溫較低,,懸浮粒子較少減低散射效果。<br/><br/><a href="http://forum.hkas.org.hk/viewthread.php?tid=3650">http://forum.hkas.org.hk/viewthread.php?tid=3650</a> <br/><br/>日行跡 - <a href="http://forum.hkas.org.hk/viewthread.php?tid=4472">http://forum.hkas.org.hk/viewthread.php?tid=4472</a> <br/><br/><script type="text/javascript"><!--google_ad_client = "pub-9426659565807829";google_ad_slot = "9359905831";google_ad_width = 728;google_ad_height = 15;//--></script><script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script>

<br/>紅外線是誰人發現的 ?<br/><br/>他就是發現天王星的威廉‧赫歇爾 William Herschel ! 1800 年赫歇爾用溫度計測量陽光經過錂鏡後的光譜,發現在紅端的光總是溫度較高的,他再把溫度計移向光譜紅端外邊的範圍,溫度又稍微上升,赫歇爾把這端不可見但有較高溫度的部份稱為 "calorific rays" ,後來改稱 infrared rays 或 infrared radiation。<br/><br/>這圖模擬赫歇爾的實驗<br/><br/><br/><br/><br/>從物理課本,我們知道太陽光譜的的強度頂點是在綠色波段 (波長 ~0.5 micron),為什麼在赫歇爾的實驗裡,最高溫度不在綠色波段而在紅外呢 ? 這網頁解釋了赫歇爾的實驗<br/><a href="http://home.znet.com/schester/calculations/herschel/index.html">http://home.znet.com/schester/calculations/herschel/index.html</a> <br/><br/>詳見這教育性豐富的網頁: <a href="http://www.ipac.caltech.edu/Outreach/Edu/Herschel/herschel.html">http://www.ipac.caltech.edu/Outreach/Edu/Herschel/herschel.html</a> <br/><br/>去年 5 月,歐洲太空局用同一火箭發射一對太空探測儀器,負責紅外線探測的一座叫 Herschel Telescope,它的單個主鏡 (3.5 米) 是太空上目前最大的,另一座叫 Planck Telescope,負責微波探測。不過兩者都須要冷凍裝置 (~零下二百度) 來達到良好 S/N 比 (signal-to-noise ratio),三數年後冷凍不足便運作失效了。<br/><br/>在太空觀測紅外線及微波比地面更有效率,因為這兩個頻段容易被大氣層的水份吸收:<br/><br/><br/>Herschel / Planck 太空望遠鏡網頁<br/><a href="http://sci.esa.int/science-e/www/area/index.cfm?fareaid=16">http://sci.esa.int/science-e/www/area/index.cfm?fareaid=16</a> <br/><a href="http://sci.esa.int/science-e/www/area/index.cfm?fareaid=17">http://sci.esa.int/science-e/www/area/index.cfm?fareaid=17</a> <br/><br/><a href="http://forum.hkas.org.hk/viewthread.php?tid=3673">http://forum.hkas.org.hk/viewthread.php?tid=3673</a> <br/><br/><script type="text/javascript"><!--google_ad_client = "pub-9426659565807829";google_ad_slot = "9359905831";google_ad_width = 728;google_ad_height = 15;//--></script><script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script>
