This is a rather general question, but the reason for this is because the car is travelling slower then the speed of sound, and so the sound of the engine and the wheels against the surface travels faster then the car itself, hence why you will hear it before the actual entity reaches you.
Because the speed of sound travels at +- 1300 km/h and the car that is approaching isn't that fast. So u first hear the sound before the car reaches u.
Thanks for the question. This phenomenon may have something to do with the fact that you may be in the approaching car's way, and they may want you to get out of the way. If the horn sounds only as the approaching car reaches you, it may be too late for anything to be done - hence most people opt for a sounding of the horn at some distance away. You hear the sound before the car reaches you because sound travels faster than the car is travelling.
The diver
Light travels much faster than sound. Light goes 186,000 miles per second. Sound travels at about 720 miles an hour. The light reaches your eye long before the sound gets there.
you can hear A very complicated process of turning waves into sound occurs in your ears
By ear because sound keep on vibrating until it reaches our ear
Light travels much faster than sound. The light from the launch reaches you almost instantly, but if you are a few miles away the sound will take several seconds to reach you.
the denser the medium the faster the sound of speed. it is experimentally proved. for example if a train is appraching and you cant hear the sound you can hear it if you put your head (ear) on the railtrack. but do move quickly if you see the train approaching.....
You hear the sound, called thunder, after the flash because light travels many times faster than sound and therefore reaches you first.
Susan and Lucy hear footsteps approaching in the snow, followed by jingling harness bells, which indicate that Father Christmas is coming.
Because light travels faster than sound. So the light reaches you first then the sound comes after.
Because the speed of light is much faster than the speed of sound. Therefore, when the light from that event reaches your eyes, you see it. Then later, the sound from the event reaches your ears, and you hear it. Basically it's just because light travels faster than sound.
