An observer sees an explosion before hearing it because light travels much faster than sound. Light travels at approximately 299,792 kilometers per second (about 186,282 miles per second), while sound travels at about 343 meters per second (around 1,125 feet per second) in air. This significant difference in speeds means that the light from the explosion reaches the observer almost instantly, while the sound takes longer to arrive. As a result, there's a noticeable delay between seeing the explosion and hearing it.
What else can I help you with?
If a satellite or spaceship explodes in outer space you can see the explosion from a distance but why can you not hear it?
Light travels in vacuum but sound cannot. So, we can see solar flares but can't hear them. (Outer space can be considered to be vacuum)
When a cannon is fired why do you see the light before you hear it?
For the same reason you see lightning before you hear thunder, Light travels faster than sound.
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
Why is the light of a distant explosion seen first before the sound of the explosion is heard?
Simply because light travels faster than sound. The speed of light is 186,000 miles per second while the speed of sound is only about 1,126 feet per second. Therefore, you see the explosion before hearing the blast. It's the same when you experience a thunderstorm - you see the lightning, and the thunder follows after a few seconds - depending how close you are to it.
On a clear night when an observer in Los Angeles sees a first quarter Moon an observer in London would see?
That person in London would see a new moon.
Explosion-do you see it first and then hear it?
You FIRST see it, then you HEAR it. The time delay depends on your distance from the source of the explosion. The explanation, light travels faster than sound.
What two physics mistakes occur when you see and hear a distant explosion at the same time?
The two mistakes are that sound travels slower than light, so if you see and hear a distant explosion at the same time, the explosion actually happened some time earlier. Additionally, the speed of light is much faster than the speed of sound, so the light from the explosion will reach you much sooner than the sound.
What two physics mistakes occur when you see and hear an explosion from outer space in movies?
1.that you see the explosion and hear it at the same time , while you should see first and here it later. 2.that sometimes there is smoke which immposible since there is no air.
How far away can you see a nuclear explosion and what factors determine the visibility of such an event?
The visibility of a nuclear explosion depends on various factors such as the size of the explosion, weather conditions, and the observer's distance from the blast. Generally, a nuclear explosion can be seen from tens to hundreds of miles away, depending on these factors.
If a satellite or spaceship explodes in outer space you can see the explosion from a distance but why can you not hear it?
Light travels in vacuum but sound cannot. So, we can see solar flares but can't hear them. (Outer space can be considered to be vacuum)
When a cannon is fired why do you see the light before you hear it?
For the same reason you see lightning before you hear thunder, Light travels faster than sound.
How do starfish know when a predator is coming?
they hear them before they see them.
How come you see lighting and do not hear it and how come you hear thunder and do not see it?
You see lightning before you hear it because light moves faster than sound. Thunder comes from the lightning. You can't hear it until the sound waves reach you.
Why can you see a meteor but not hear it?
Because it generates no sound. The only time it would make a sound is if it was big enough to pass through the atmosphere, and strike the Earth. In which case, you would hear something similar to an explosion.
What are the verbs in this sentence You can hear the train long before you saw it?
Can hear and saw are the verbs, but "saw" should be "see".
To crush your enemies See them driven before you and to hear the lamentation of their women?
Yes
Examples to show that light travels faster than sound?
An example that shows light travels faster than sound are: - You see the lightning before you hear the thunder. - You see the light coming from the lighthouse before you hear the foghorn. Unless the storm is right overhead, you will see the lightning before you hear the thunder. An experiment you can do to prove that light travels faster than sound is you can ask your friend to turn on a torch and make a huge noise at the same time from quite a distance from where you are standing. If you have a large distance between you and your friend, you will probably see the light before you hear the sound.
