If thunder and lightning occur together close to you, you are dangerously close to a lightning bolt.

Why is lightning seen before sound of thunder is heard even though both occurs simultaneously during thunder storms?
Because the speed of light is faster than the speed of sound. In fact, light arrives at the observer virtually instantaneously, but sound takes almost 5 seconds to travel each mile. It's simple to observe lightening then count seconds until the thunder is heard to estimate the distance.

If thunder is the sound of lightning could you make an instrument that will allow you to make light and sound in a similar way?
Answer 1 Yes, John Dennis (1657 - 1734) devised a thunder and lightning stage effect for one of his plays which was a flop. He went to a performance of Macbeth and heard his effect being used, which led him to say "Damn them! They will not let my play run, but they steal my thunder!" Yes, but not in the way you mean - thunder is the sound of the air being ripped apart when lightning strikes. The jump of the spark from the clouds to the ground creates a pressure wave in the air that we percieve as sound and refer to as thunder. You could make an instrument that creates lightning like sparking, but the sounds would be popping and buzzing. The instrument would probably be a Tesla coil. Answer 2 It has been a lot of years since I had any science classes, BUT my recollection suggests that answer 1 is incorrect, in that the sound wave is not generated when the air is "ripped apart." As I understand the process, the lightening bolt [an electrical ARC] ionizes a column of air, which results in great HEAT and THERMAL EXPANSION of the air within the column. Then when the expanded air rapidly cools, it rapidly "shrinks," and the COLLISION of the air molecules RETURNING TO FILL THE VOID, creates the shock wave that we hear as a thunder "clap." As answer 1 indicates, ANY spark discharge creates a sound. The ONLY difference in sound VOLUME between a lightening bolt and a static spark [as between your fingertip and a doorknob] is the amount of energy discharged in creating the arc. Research facilities have been generating man-made lightening bolts for years. And, YES you could make an "instrument" to accomplish the same thing, IF you have enough money and knowhow. Answer 3 Yes. There is video of such an instrument here: http://www.youtube.com/watch?v=o_PHLUvDZSg Answer 4 If you check out the video in answer 4, note that the "Super Mario Theme" music soundtrack has been added, and what is the subject of the demonstration : music. The arc [spark] "sound" is being fed to an amplifier, which is coupled to the static electric generator, using the music to modulate the static discharge ["lightning"]. The only sound of the arc discharge can only be heard during the first 10 seconds of the video, until they start the music audio input signal. The original question says "make light and sound in a similar way?" The Van der Graf static electric generator in the video is only capable of creating a microscopic "lightning bolt" accompanied by a "microscopic" "thunder clap" [heard only a "sizzling" static sound]. Again, a true monster discharge arc could be generated, IF one had enough money for equipment, and the knowledge to create it. The technology and ability to do so has been around for a long time. Until someone is willing to spend a fortune to accomplish it, we will have to be satisfied with microscopic demonstration models such as the Van der Graf generator. Answer 5 A respectable home made flash + bang lightning device can be made for nearly nothing. To get a firecracker type bang all that is needed is the flash circuit from a disposable camera, a short piece of plastic pipe, three screws and some wire. The spark length is typically a few millimeters long and, as I said, about as loud as a firecracker. Google "trigatron" for construction details. Answer 6. Lightning is about 10 times hotter than the surface of the sun. When a lightning bolt passes through the air it heats it very rapidly, thus causing the air to rapidly expand and compress. This compression is what we hear as thunder.
What is a flash band in horse tack?
It is a part on a flash bridle.
When was Flash Mob America created?
Flash Mob America was created in 2009-07.
Why would you have to watch out if the flash of lightning and the sound of thunder seem occur together?
If thunder and lightning occur together close to you, you are dangerously close to a lightning bolt.
Why would you have to watch out if the flash of lighting and the sound of thunder seemed to occur together?
The closer together the flash and thunder occur, the nearer the storm is to you.
Does thunder have a flash?
No. Lighting produces a flash. Thunder is the sound the lightning produces.
What is a flash of lightning and the thunder that follows?
thunderstorm
What is flash of lightning and the thunder that follows?
thunderstorm
How is thunder produced and how far away does the lightning strikes if the thunder is heard 15 seconds after the lightning is seen?
Thunder - is the result of a lightning flash. The flash causes the surrounding air to move away from the source at 300 metres/second. An approximate calculation for the relationship between the lightning flash to hearing the thunder, is 5 seconds per mile.
Does thunder cause lightning or does lightning cause thunder. Explain?
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.
What is The loud crashing or rumbling noise heard after a flash of lightning?
Thunder
Why are you hearing thundering after lightning?
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.
Why does thunder ussually occur during storms that have lightning flashes?
The thunder is the sound of lightning but you only hear the thunder after the flash because lightning is faster than the speed of sound.
Why do sometimes hear thunder at about the same time you see flash of lightning but other times you hear thunder after the flash?
If you hear the thunder almost at the same time as the lightning flash - the storm is directly overhead. Usually - the sound of thunder arrives a few seconds after the lightning, because light travels much faster than sound.
You hear thunder 13.9 seconds after a lightning flash how far are you from lightning?
then the lightning is 2.78 miles away from you.
