Thunder is heard after lightning is seen because lightning produces a rapid expansion of air, creating shock waves that we hear as thunder.
Lightning travels at the speed of light, which is much faster than the speed of sound. When lightning strikes, the light reaches us almost instantaneously, while the sound takes longer to travel to our ears, resulting in a delay between seeing the lightning and hearing the thunder.
thunder is caused when lightning travels over the speed of sound making a sonic boom. also the heat is so enormous it fries the air and ground below it. technically speaking lightning travels from the ground and clouds and meets in the center.
lightning bolts can occur during a thunder storm.
Lightning is a form of electrical energy that results from the buildup and discharge of electrical charge in the atmosphere, typically during thunderstorms. It is a powerful and sudden release of stored energy that can be seen as a bright flash of light and heard as thunder.
The word 'thunder' is both a verb and a noun.Examples:When it began to thunder, we decided to go home. (verb)We heard the thunder but didn't see any lightening. (noun)
No, lightning is seen before thunder is heard. The speed of light is faster than the speed of sound, so light from the lightning reaches us first, followed by the sound of thunder a few seconds later.
When lightning appears in the remote distance and appears to produce no thunder sound, it is popularly known as "heat lightning." Meteorologists will tell you that there really is no such thing as a distinct type of lightning that is not followed by thunder. All lightning produces thunder, but it is only audible for a distance of some 15-20 miles from the storm. At night, lightning can be seen for distances of up to 125 miles if the conditions are right. So when lightning is seen but no thunder is heard, you are simply too far away from the storm.
the lightning was 0.8 miles away.
The answer is a storm. Lightning is seen before thunder, which is heard before rain, which falls from the clouds during a storm.
Thunder is the sound heard after lightning.
Thunder - is the result of a lightning flash. The flash causes the surrounding air to move away from the source at 300 metres/second. An approximate calculation for the relationship between the lightning flash to hearing the thunder, is 5 seconds per mile.

Surely you have heard thunder and seen lightening during a storm - what you can see and measure is fact not myth.
Light travels faster than sound
The loud noise heard after lightning is thunder. Thunder is caused by the rapid expansion and contraction of air surrounding a bolt of lightning, creating a shock wave that we hear as a booming sound.

Thunder is the loud crashing or rumbling noise heard after a flash of lightning. This happens because lightning heats the air around it, causing it to rapidly expand and create a shock wave that we hear as thunder.
