pein 10 Posted January 3, 2014 Report Share Posted January 3, 2014 冬季時,台灣23.5度,則正午的太陽仰角是90-(23.5+23.5)為甚麼? Link to post Share on other sites
司馬特 12 Posted January 3, 2014 Report Share Posted January 3, 2014 夏天的中午太陽直射台灣 所以太陽在天空的正上方 仰角90度春天和秋天太陽直射赤道 所以太陽的仰角是 90-23.5 度冬天太陽直射南回歸線 太陽的仰角就是 90-(23.5+23.5)度了 Link to post Share on other sites
嵐月銀牙 10 Posted January 8, 2014 Report Share Posted January 8, 2014 這是個簡單的幾何關係，把圖畫出來(樓上那張圖那樣)，用一些同位角之類的概念就可得知原因了XD Link to post Share on other sites
