Thunder+and+Sound

Thunder and Sound Josh E Thunder is the Sound caused by lightning. Depending on the nature of the lightning and distance of the listener, thunder can range from a loud sharp crack, to long low rumble. Thge sudden increase in pressure and temperature from lightning produces rapid expansion of the air surrounding and within a bolt of lightning. In turn, this expansion of air creates a sonic shock wave which produces the sound of thunder

Thunder has been a mystery for many centuries to many scientists, wondering what the real cause of thunder is. Aristotle came up with the first theory that thunder came from the collision of large clouds. After many theories and ideas an accepted theory has been found in the mid 1900's. The theory is that thunder must begin with a shock wave in the air due to the sudden thermal exspansion of the plasma in a lightning channel.

Thunder relates to sound and waves becasue it leterakky is the sound of lightning, and is produced from a shock wave from a lightning channel.

 * A flash of lightnin, followed after some seconds by a rumble of thunder illustrates the fact that sound travels significantly slower than light. Using the difference, one can estimate how far away the bolt of lightning is by timing the interval between seeing the flash and hearing the thunder. The speed of sound is approximatly 768 mph.
 * The temperature inside lightning is approximatly 20 000k - 30 000k.
