動畫:折射定律(law of refraction)與全反射

此動畫呈現光線從空氣射至透明界面時,我們可以觀察到部份反射,部分透射的現象. 其中透射的光線會有偏折的情形,由參考圓的正弦長度比或角度的正弦值(sin)比, 可了解各物質對光的偏折特性與程度. 當光線由介質–>空氣(光密介質到光疏介質)時,會有"全反射"現象. [其中反(透)射光強度為示意摩擬值] 拖曳入射光可改變光入射角度. 拖曳參考圓可改變其半徑.

<<因目前網路已不支援 flash 播放 , 建議到官網下載Flash Player Projector(或下載下列表單中選擇您系統的執行檔) 執行該程式>>檔案>>開啟後 , 將各動畫網址複製貼上,即可瀏覽動畫.點選參考使用說明>>
