#SPEED OF SOUND VS SPEED OF LIGHT CRACK#

Why do we see lightning before the thunder? In a small plane called the X-1, he was the first person to fly faster than the speed of sound and the listeners on the ground were the first to hear the loud shock wave of a sonic boom. On October 14, 1947, Chuck Yeager did just that. When a plane does go faster than speed of sound, it is said to break the sound barrier and a sonic boom is produced. That is the same as a car traveling about 780 miles per hour! Even most jet airplanes do not travel that fast. The speed of sound through warm air at sea level has been measured at 346 meters per second or 0.346 km per second. The longer it takes to hear the thunder, the farther the distance its sound had to travel and the farther away the storm is. Based on how much longer it takes to hear thunder tells us how far away the storm is. We see the lightning almost instantaneously, but it takes longer to hear the thunder. Lightning and thunder both happen at the same time. The same thing is at work during a thunderstorm. This is because the speed of sound is slower than the speed of light, which we are used to seeing. Or, you saw the drummer strike the drum, but it took an extra moment before you heard it.

#SPEED OF SOUND VS SPEED OF LIGHT CRACK#

You saw the batter hit the ball, but did not hear the crack of the impact until a few seconds later. If you have ever been to a baseball game or sat far away from the stage during a concert, you may have noticed something odd.
