Question

Why does it always thunder right after lightning flashes?

Answer 1

Lightning causes thunder because a strike of lightning is incredibly hot. A typical bolt of lightning can immediately heat the air to between 15,000 to 60,000 degrees Fahrenheit. That's hotter than the surface of the sun!  

A lightning strike can heat the air in a fraction of a second. When air is heated that quickly, it expands violently and then contracts, like an explosion that happens in the blink of an eye. It's that explosion of air that creates sound waves, which we hear and call thunder.  

When lightning strikes very close by, we hear the thunder as a loud and short bang. We hear thunder from far away as a long, low rumble.  

Lightning always produces thunder. When you see lightning but don't hear any thunder, the lightning is too far away from you for the sound waves to reach you

Answer 2

if you're right by the epicenter of where lightning strikes, thunder and lightning would be simultaneous.. there is delay in thunder sound between lightning due to distance you are from it.

Answer 3

Because sound only travels at 1108 feet per second. Light travels at  983, 571, 056.43 feet per second.  Sound is soooo slow.

Answer 4

To make a long story short, light travels faster than sound. It takes long to here the sound of a thunder boom than to see a lightning strike.  

Answer 5

The speed of sound is faster than the the speed of sound. Think, when you speak & when you turn a light on. Which is the faster?

You turn a switch on, it takes a couple seconds for the light to come on, when you speak, it's almost instantly.

I remember this from grade school.
