you can see lightning
If you see lightning but don't hear thunder, it means the lightning is far away. The speed of light is much faster than the speed of sound, so you usually see lightning before you hear the associated thunder.
Thunder and lighting do occur together during a thunderstorm. Lightning is a sudden discharge of electricity in the atmosphere, which creates the bright light that we see, while thunder is the sound created by the rapid expansion of air around the lightning bolt. Light travels faster than sound, so we see the lightning before we hear the thunder.
A lightning flash travels at the speed of light. The sound of thunder travels much slower. Therefore, we see the flash before we hear the thunder.
Thunder is caused by the rapid expansion and contraction of air surrounding a lightning bolt. While thunder is typically associated with lightning, it is possible to hear thunder without seeing the associated lightning if the lightning is occurring far away or behind clouds. This phenomenon is known as "heat lightning."

Lightning causes thunder. Lightning is a massive electrical discharge that you see as a bolt or flash of light. Thunder is the sound caused when the lightning superheats the air, creating a shockwave.
You see the flash of lightning before you hear the thunder because light travels faster than sound. The light from the lightning reaches your eyes almost instantly, while the sound of thunder takes longer to travel through the air to reach your ears.
Thunder and lightning occur roughly at the same time during a thunderstorm, but they are different things. Typically you see the lightning first and then you hear the thunder.
No, thunder reaches the observer after they see lightning.
You often hear thunder when you see lightning because lightning produces a sudden and rapid heating of the air around it, causing it to expand quickly. This rapid expansion creates a shock wave that we hear as thunder. The farther away you are from the lightning, the longer it takes for the sound to reach you.
You see lightning first because light travels faster then sound.Also, you don't see thunder - you hear it.
You can see lightning but you cannot hear it directly. The sound you hear is thunder, which is created by the rapid heating and cooling of air surrounding a lightning bolt.
If you see lightning but don't hear thunder, it means the lightning is far away. The speed of light is much faster than the speed of sound, so you usually see lightning before you hear the associated thunder.
Thunder is our name for the sound made by lightning. The reason there is (usually) a delay between when you see the bolt of lightning and hear the thunder is that light travels more quickly than does sound. This is the reason that you can count seconds between seeing lightning and hearing thunder to figure out how close the lightning is to you. When the lightning is closer to you, the sound doesn't take as much time to travel to your ears and thus the gap between the lightning and thunder is shorter. So you can't see thunder because it's merely a sound - but you can see the source of that sound.

I think the appropriate wording for this question: "why do you see lightning before hearing thunder?" The simple answer is that light travels faster than sound.
