從3.09公裏以外來的閃電與雷鳴
Lightning and Thunder
At around 6:40 pm, 7/1/2025
Camera: Sony FDR AX53
從錄的22分鍾像裏選出的一分鍾
Software: Adobe Premiere Elements 2024
閃電與雷鳴的發生處應該是離我3.09 km 遠的地方。
計算方法:
假定閃電與雷鳴同時發生,因為它的速度快,394289.28 公裏/小時(我們選245000 miles/hr),我們立刻看到閃電,然後聽到雷鳴,因為聲音在空氣中傳播速度遠比光慢,343 米/秒。9秒*343 米/秒=3087米
The lightning was at 0:24 and the thunder was at 0:33,so the lightning and thunder were 3.09 km (9s x 343 m/s(sound speed in the air))from me.
