Both lightening and thunder occur at the same time, but the sound of thunder is heard after lightening is seen because light travels faster than sound. While lightening may be seen for miles, thunder is seldom heard beyond a 10-mile radius.Know More
When lightning travels from clouds to the ground, it opens a little hole, or channel, in the air. Once the lightening disappears, the hole collapses and reverts back inwards. The resulting sound is thunder. Light travels at a rate of 186,282 miles per second, allowing the human eye to see a flash of lightning immediately as it happens. Sounds travels at the much slower rate of 1,087 feet, or one-fifth of a mile per second.
The rate at which the sound waves travel varies, depending on the temperature of the air and the wind's speed. Thunder appears to rumble or roll at times due to zigzag lines, or forks, that occur when lightning that strikes is not visible. These forks can branch out over several miles. These branches of lightning are further from the ground; therefore, they produce sounds of thunder, which take longer to be heard than the large bolt of lightning that originally produced the branched-out forks.Learn more in Storms
A bolt of lightning travels at approximately 224,000 miles per hour or approximately 3,700 miles per second. Lightning is a discharge of static electricity that has accumulated as a result of collisions between ice particles in storm clouds.Full Answer >
Thunder is the sound created when lightning passes through the air, causing it to rapidly heat and cool, resulting in a massive pressure wave that can be heard. A single lightning bolt can raise the temperature of the air around it as high as 50,000 degrees Fahrenheit.Full Answer >
In its simplest form, thunder is the result of a shockwave that breaks the sound barrier. Thunder forms as the air around a bolt of lightning becomes superheated and explodes, producing a shockwave. This shockwave travels faster than the speed of sound, which produces a sonic boom, just as a fighter jet does when it travels faster than the speed of sound.Full Answer >
Thunder comes from the rapid movement of air in a lightning bolt. Due of the speed at which lightning bolts travel, the surrounding air does not have enough time to expand. This compressed air creates a shock wave similar to an explosion, causing thunder.Full Answer >
