💡 為什麼發明藍色的 LED 燈這麼困難?
Why Was the Blue LED Almost Impossible to Make?🧠 好奇問題:為什麼科學家在發明紅色和綠色 LED 之後,還要花三十年的時間才能做出藍色的光呢?🎧 這一集在聊什麼:我們要認識工程師中村修二的故事,看他在大家都認為不可能的時候,如何利用自己改裝的機器做出第一顆亮藍色 LED。小朋友會學到,有了藍色光之後,我們才能組合出紅色、綠色以外的其他顏色與白色光,並讓現在的手機、電視螢幕和省電燈泡變得可能。👦👧 適合誰收聽:適合國小生收聽,也很適合爸媽陪孩子一起聽、一起討論。🎙️ 節目介紹:這裡是《你想學什麼呢?》,一個用簡單、有趣的方式,陪孩子探索世界各種為什麼的 Podcast。🧠 Curiosity question:Why did scientists have to wait thirty years to create a blue LED after they had already invented red and green lights?🎧 What this episode is about:We follow the journey of engineer Shuji Nakamura, who built his own equipment to solve the mystery of the blue LED when…
