You SEE things at the speed of light (186,000 miles per second) but you HEAR things at the speed of sound- about 1/5 of a mile per second. The light gets to you long before the sound.

Is gun sound and smoke produced at the same time?
The smoke is produced slightly before the sound. Smoke is produced by the ignition of the propellant in the round. The sound is produced when the bullet passes through the sound barrier.
From the stands of a race track why do you notice smoke from the starter's gun before you hear it fire?
Light travels faster than the sound. Light from the sun reflects off the smoke to your eyes at a rate of 300 000 000 m/s, while the sound from the gun (happening at the exact same time as the reflection of light off the smoke) travels at only 340 m/s. Therefore, the light will reach your eyes before the sound reaches your ears.
Why do you watch for smoke as opposed to the sound of the gun?
Speed of light is faster than speed of sound.
What would happen first hear a gun shot or see a gun shot?
See it- speed of light, then hear it- speed of sound is MUCH slower.
How do you spell soud?
If you mean a noise humans hear, it is spelled sound. The gun made a loud sound.
Can a bullet exit a gun before you hear the blast?
Yes, it is will happen that way. The sound of the blast is caused by the release of gasses at the muzzle of the gun. Those gasses are trapped behind the bullet- pushing it- and are not released until the bullet leaves the gun.
Why the flash of the gun reaches as before the sound of the gun?
Because light moves substantially faster than sound.
Would you be able to hear a gunshot if you were shot by a bullet?
Yes, you would. Interesting enough however, since most bullets travel faster than the speed of sound, you would actually be hit by the round slightly before you hear the gun fire.
Why do you hear a sound when you shot a gun?
Rapidly expanding gas from burning gunpowder makes a pressure wave in the air.
Do the streamline darts for Nerf guns make sound?
No. They don't. There is a sound that can be quite loud, but that comes from the gun. Any noise you hear will come from the gun. So, if you are trying to sneak up on someone, they won't realize until you shoot.
Why are ears useful for athletes?
