2026newtalk 國中生物 單元五: 後像的奧秘
from 雷比特生物空中講 · host 雷比特老師
深入淺出地解釋人類視覺中「後像」產生的兩種科學原理。第一種是「正片後像」，又稱作視覺暫留，其成因在於視網膜神經的慣性，使我們能將閃爍的靜止畫面轉化為連貫的電影動畫或煙火殘跡。第二種則是「負片後像」，源於視錐細胞長時間接收單一色彩刺激後產生的視覺疲勞，導致大腦在注視空白處時呈現互補色的影像。最後透過手術室醫護人員穿著綠色制服的實例，展示如何利用科學知識解決生活中因生理限制所帶來的干擾。這份來源不僅釐清兩者在顏色表現與成因上的本質差異，更揭示大腦處理影像時並非即時同步的有趣真相。 聽完後可以自主進行線上測驗，檢視學習成效喔~(需要登入gemini) 測驗網址 https://gemini.google.com/share/5b4b47f34105 Powered by Firstory Hosting
