Sound (thunder) travels much much slower than light (lightning flash).
Thunder is heard after lightning is seen because lightning produces a rapid expansion of air, creating shock waves that we hear as thunder.
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.
Heat lightning does not touch the ground during a storm. It is a type of lightning that occurs high in the sky and is often seen in the distance, appearing as a flickering glow without thunder.
You can tell that sound waves and light waves travel at different speeds during a thunderstorm by observing the delay between seeing lightning and hearing thunder. Light travels much faster than sound, so the lightning is seen almost instantly while the thunder takes longer to reach you. This delay in the arrival of sound waves compared to light waves demonstrates their different speeds of travel.
Heat lightning is actually a weather phenomenon and not a form of lightning. It refers to the distant flashes of lightning that can be seen on the horizon during a hot summer night, without the accompanying thunder because the storm is too far away. The irony lies in the term "heat lightning" as it has no actual connection to heat, but rather to the distant lightning strikes.
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.
Thunder is heard after lightning is seen because lightning produces a rapid expansion of air, creating shock waves that we hear as thunder.
The answer is a storm. Lightning is seen before thunder, which is heard before rain, which falls from the clouds during a storm.
Light travels faster than sound
It isn't ! A flash of lightening is seen BEFORE a peal of thunder is heard.
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.
Light travels faster than sound, so lightning is seen before thunder is heard. The time lapse between seeing the lightning and hearing the thunder depends on how far away the storm is. Each second between the flash and the sound represents about 0.3 kilometers (0.2 miles) of distance.
No. Thunder is the result of lightning when it hits the ground. After lightning hits the ground the air expands (because of the increase in temp.) and quickly condenses. That air condensing is what we hear when there is thunder. Because light travels faster than sound we see lightning then hear thunder.
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, so when lightning strikes, the light is seen immediately while the sound takes time to reach our ears. The delay in hearing the thunder allows us to calculate the distance of the storm based on the time difference between seeing the lightning and hearing the thunder.
