从3.09公里以外来的闪电与雷鸣
Lightning and Thunder
At around 6:40 pm, 7/1/2025
Camera: Sony FDR AX53
从录的22分钟像里选出的一分钟
Software: Adobe Premiere Elements 2024
闪电与雷鸣的发生处应该是离我3.09 km 远的地方。
计算方法:
假定闪电与雷鸣同时发生,因为它的速度快,394289.28 公里/小时(我们选245000 miles/hr),我们立刻看到闪电,然后听到雷鸣,因为声音在空气中传播速度远比光慢,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.
