How long does it take thunder to come after lightning?
Thunder and lightning happen at the same time as thunder is the sound produced by lightning. Light travels much faster, but sound travels approx. 340m/s, so there will be 1 second between seeing the lightning and hearing the thunder for every 340m you are from the lightning.
How many seconds would it take you to hear the thunder if the lightning were 1 kilometer away?
The answer to this question would be .625 seconds away.
What does it mean if you see a flash of lightning and clap of thunder at almost the exact same time?
Just for fun: If you see a clap of thunder, call a journalist! More seriously, if you see a flash of lightning and hear a clap of thunder at almost the same exact time, it means that the electrical discharge that generated both the lightning and the thunder is very close to you, and you should take precautions immediately to avoid injury to yourself. Usually, the most practical precaution is to seek shelter in a building protected by lightning rods or a metal vehicle that will conduct electricity around you more readily than through you!
When does lightning become visible?
Lightning is the result of air molecules being superheated (up to approximately 54,000° F, or six times the surface temperature of the sun!) by a massive surge of electricity. As such, lightning is always visible if you're close enough, though it may be obscured by opaque and semi-opaque materials such as clouds, smoke, soot, heavy snow, tornadic debris, etc.As a general rule of thumb, if you're close enough to hear the thunderclap, you were probably close enough to see the lightning. (And if you can hear thunder, you're at risk of being struck by lightning, so take shelter immediately.)
Why lightning has no sound?
Lightning does have sound. Depending upon the distance of the lighting bolt, it may be audible instantaneously or it may take several seconds for the sound waves to reach your ears. The further away the lighting, the longer it will take for the thunder to follow.

Why can't you see 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.
How long does it take for lightning to travel?
5 sec A typical lightning strike is over in a few milliseconds. The thunder travels at the speed of sound.
Why did people hear a loud rumble before the shaking began in christchurch?
P waves are also faster than S waves, and this fact is what allows us to tell where an earthquake was. To understand how this works, let's compare P and S waves to lightning and thunder. Light travels faster than sound, so during a thunderstorm you will first see the lightning and then you will hear the thunder. If you are close to the lightning, the thunder will boom right after the lightning, but if you are far away from the lightning, you can count several seconds before you hear the thunder. The further you are from the storm, the longer it will take between the lightning and the thunder. P waves are like the lightning, and S waves are like the thunder. The P waves travel faster and shake the ground where you are first. Then the S waves follow and shake the ground also. If you are close to the earthquake, the P and S wave will come one right after the other, but if you are far away, there will be more time between the two.
What is the difference between lightning and thunder?
Thunder is what you hear, lightning is what you see, but both are due to electrical discharge in the atmosphere. They can seem to be separated in time to an observer (you see the lightening before you hear the thunder) because of the large difference in the speed of sound and the speed of light. If you are significant distance away (a few miles or kilometers), the light from the discharge will reach you almost instantly, but the sound can take several seconds to arrive. In fact you can measure the distance from you to the lightening in this way: for each second delay between seeing it and hearing it, the lightening bolt is approximately 300 meters, or 1000 ft away. Thunder is merely the rumbling sound that lightning creates. You hear the thunder after you see the lighting because light travels faster than sound. Lightning is the light that is emitted, and thunder is the sound.

How long does it take lightning to go around earth once?
The radio waves from a lightning stroke travel at the speed of light, you can hear them as clicks on a long-wave radio, and they travel round the world in 1/7th of a second.
When does 'Roll of thunder hear my cry' take place?
The setting is the Mississippi countryside in 1933.
How does sound travel why don't i hear thunder at the same time as i see lightning?
This is because light travels faster than sound. Light travels so quickly that when a bolt of lightning occurs, you see it immediately. Sound moves at a few hundred miles per hour, meaning that it will usually take a few seconds for the thunder to reach you unless the lighting bolt was very close.
