"雷{かみなり}" is thunder, or lightning, or both?


  * In daily conversation, " **雷** " means both the lightning and the accompanying thunder as a single phenomenon, right? 
  * At night, I sometimes see lightning on the horizon, but no thunder. That is 雷, right?
  * All the time, I hear the thunder, but not see the lightning. That is also 雷, right?
  * Does "雷を見えた？" sound like natural Japanese?
  * Does "雷を聞こえた？" sound like natural Japanese?




Yes, 雷 refers to both the lightning and the sound caused by it.

If you need to distinguish, the specific term for the visible discharge of the
light is 稲妻【いなずま】, and the specific word for the sound is 雷鳴【らいめい】. Although
these words often appear in news media and scientific papers, we usually just
use 雷 in everyday conversations.

As for the last two questions, the natural ways to say them are "雷( **が**
)聞こえた?" and "雷( **が** )見えた?". "が" is often omitted in conversations, and we
don't use "を" there.
