Why does the fireworks sound come after a second of an explosion?

The explosion and the 'bang' happen at the same exact time !
But the light from the burst has to travel to you before you can see it, and the sound of the burst has to travel to you before you can hear it.
Light travels much faster than sound ... about 874,000 times faster ( ! ) ... so the light always reaches you before the sound does. You always see the burst before you hear it.
The farther you are away from it, the farther the sound will lag behind the light, and the more time there will be between the sight and the sound. From one mile away, the sound reaches you about 5 seconds late.
Rule of thumb for audio is 1 millisecond per foot, it takes about 30 ms delay (30 ft)before most humans can percieve the delay

∙ 5y agosound travels at about 1000 feet per second, so if you are 1000 feet awy it takes a second to hear the sound; the light from the fireworks travels much much faster so you see it right away, but do not hear the sound right away.

∙ 5y agoThe visible light that we see as the explosion travels at the speed of light, which is 300,000,000 m/s, and the speed of sound is about 340 m/s. So it takes longer for the sound to reach you.

∙ 5y agoLight travels very much faster than sound: 300,000,000 metres per second compared to 340 metres per second. So the flash of an explosion is seen almost instantaneously whereas the sound can take a while to get to you..

When gas and fire come together what makes the explosion?
An explosion is caused by fuel burning very rapidly. The products of combustion expand rapidly and with extreme force, and the result is what we call an explosion. So...if you put gasoline on a fire and it explodes, as it will, the explosion was caused by the fire.

Would fireworks still look round when watched from the side?
Ever see a firework explosion that WASN'T round? Everytime you see a fireworks explosion, you are seeing it from the side. The "side" you see is not the same side someone 200 yards away would see. Nor is it the same side someone a mile and a half away would see. Think of a lightbulb. When you turn the switch, an "explosion" of light particles is ejected from the filament. The particles of light all come from the center and travel at the same relative speed in every direction. In a fireworks explosion the same thing happens. A small center (the filament) explodes and sends tiny particles of burning matter, all moving at the same relative speed, in all directions making a "ball" of light. Just like a basketball, no matter what side you look at, it's round. There's an exception to this answer==If it is a kind of breezy night--The Fire works don't always fall straight to the ground--They sort of float in one direction==Not staight down!!Al;so did you ever view fire works from up in an airplane==Very different!!

When your heart pounds what is making the sound come from your heart?
The sound coming from your heart is the sound of the valves in the heart closing and the turbulence in the blood that results. In a normal healthy adult the first sound (or lub) is from the closing of the AV valve and the second sound (or dub) is from the closing of the semilunar valve.
