The time it takes to hear thunder after lightning strikes is typically about 5 seconds for every mile of distance between you and the lightning.
thunder is caused when lightning travels over the speed of sound making a sonic boom. also the heat is so enormous it fries the air and ground below it. technically speaking lightning travels from the ground and clouds and meets in the center.
"During a storm, thunder is caused by the rapid expansion and contraction of the air surrounding a lightning bolt. The incredible heat of a lightning bolt (nearly 50,000 degrees Fare height) causes the air around the bolt to become super heated. Thus, the air suddenly expands, in less than a fraction of a second. However, the air cannot stay super heated very long. The heat dissipates quickly through the air, causing compression waves that we hear as thunder."
No, you do not have to be directly in front of an object to hear a sound. Sound waves can travel in all directions, so as long as you are within range of the sound source, you will be able to hear it.
Long waves due to lightning has lowest frequecy. Apart from light produced an electrical disturbance in the form of electromagnetic waves are also accompanied with the lightning.
Without a doubt, Florida. There are very good meteorological reasons for this: it is close to the tropics (which have prodigious amounts of warm moist air masses), and ocean water literally surrounds it. In fact, Cape Kennedy spaceport has a huge problem with the statistical likelihood of lightning damaging space vehicles and support equipment. So-called 'anvil forecasting' is essential to space launch safety, and there has only been limited research in this area. A lightning hit to a rocket during launch phase can easily destroy it. Because liquid fuel loaded into sitting space vehicles must be pumped back out, it costs a large amount to scrub a launch. Better long term forecasting of convective storms (i.e. thunderstorms) would help improve launch planning.
If you hear thunder long after seeing lightning, it indicates the storm is moving away from you. Thunder is the sound produced by lightning, so the delay suggests the storm is at a significant distance. As long as the delay is significant enough, the risk of being struck by lightning is greatly reduced.
For a long time it was thought by many people that the number of seconds after the lightning strikes is the miles the center of the storm is from you. Although this does show how light travels faster than sound, this system is wrong. The actual method for finding the distance the heart of the storm is from you is by counting after you see lightning; and stop counting after you hear the thunder. Now, for every five seconds after the lightning struck until you hear the thunder, it is one mile away. So if ten seconds go by between lightning and thunder, the center of the storm is two miles away.
While lightning produces very high temperatures, the amount of air it heats is fairly small. In most cases a bolt of lightning is a few miles away, too far away to feel the heat. People have felt the heat from lightning, but only when it struck dangerously close.
Only a portion of the discharge of electricity actually grounds itself during the strike. The bolt continues to surge through the cloud it emerged from long after the initial burst, generating the continuous thunder. A lightning storm when viewed from inside the charged cloud, can be quite the experience because of this.
If it is a thunderstorm, you check how long it takes to hear the thunder after you see a lightning strike. For every five seconds, the lightning strike is about one mile away. The lightning causes the thunder, and the sound travels at a speed of about one mile per five seconds.
it depends on what it strikes
