Lightning can hit the Earth, or in some cases COME from the Earth and go up depending on local electric gradients. The flow of electrical charge causes light, but the speed of that flow is MUCH less than the speed of light. In comparable media, NOTHING can exceed [or even equal] the speed of light, as described in the Special Theory of Relativity. A mass will grow to enormous, mind boggling values as it approaches the speed of light, because of a term in the equation (1 - v/c) in the denominator which makes the value approach infinity as v/c approaches 1, so 1-1 = 0 and you approach dividing by zero. v takes values starting from zero almost up to c, the speed of light in a vacuum.
What else can I help you with?
Why do we hear thunder a few seconds after seeing lightning?
Light travels faster than sound.
Why does lightning first?
The speed of light is faster than the speed of sound, therefore you see lightning first during a thunderstorm, then you hear the thunder. *yikes!* :) ilovecatz1234
Why do you hear thunderclap after a lightning flash?
Because light travels faster than sound. So the light reaches you first then the sound comes after.
Why don't the thunder and lightning come together?
Thunder and lighting do occur together during a thunderstorm. Lightning is a sudden discharge of electricity in the atmosphere, which creates the bright light that we see, while thunder is the sound created by the rapid expansion of air around the lightning bolt. Light travels faster than sound, so we see the lightning before we hear the thunder.
Why do we hear thunder some seconds after seeing the lightning?
In simple terms... light travels much faster than sound. We see the lightning flash first, followed by the sound when it finally reaches us
Which travels faster noise or lightning?
lightning travels faster. Light is faster than sound.
Why is it that lightning travels faster than sound?
Light speed is much faster than the speed of sound, ergo the light you see in lightning is visible, before you here the sound.
How does thunder and lightning link to the travelling of sound and light?
it faster than sound
Which of these two is faster is it lightning or thunder?
The lightning. The speed of light is faster than the speed of sound. In addition, lightning creates thunder, therefore it happens first, therefore must be faster. See the related link for more information.
Why do you see lightning before you hear it?
light travels much faster than sound
Is lightning or sound faster?
Lightning. Because it is the speed of light.
Why do we hear thunder a few seconds after seeing lightning?
Light travels faster than sound.
Information about light?
Light travels more faster than sound that is the reason why you can SEE lightning before you HEAR thunder
When lightning occurs you first see the light and then hear the sound why?
Really? Cause light travels faster than sound.
Why do you see the lightning first if you are far away?
Because light travels much faster than sound.
Why do you see a lightning flash before you hear it?
Because the speed of light is faster than the speed of sound.
Why do you see lightning before you hear the thunder it makes?
Lightning is seen first because light travels much faster than sound.The light from the lightning reaches you almost instantly, while the sound of thunder travels much slower through the air, resulting in a delay between seeing the lightning and hearing the thunder.
