Light always travels at the speed of light. The only time that's 299,792,458 meters per second ( " c " ) is when it's traveling in vacuum.
First of all, let's get our constants straight. "Miles" is not a speed, and thespeed of sound is not 330 miles per anything. 330 meters per second is areasonable value to use for the speed of sound.1,500/330 = 4.545 seconds.(rounded)
Because the speed of light is faster than the speed of sound. In fact, light arrives at the observer virtually instantaneously, but sound takes almost 5 seconds to travel each mile. It's simple to observe lightening then count seconds until the thunder is heard to estimate the distance.
Thunder is our name for the sound made by lightning. The reason there is (usually) a delay between when you see the bolt of lightning and hear the thunder is that light travels more quickly than does sound. This is the reason that you can count seconds between seeing lightning and hearing thunder to figure out how close the lightning is to you. When the lightning is closer to you, the sound doesn't take as much time to travel to your ears and thus the gap between the lightning and thunder is shorter. So you can't see thunder because it's merely a sound - but you can see the source of that sound.
Radio waves form part of the electromagnetic spectrum (which includes all light). They therefore travel at the same speed as x rays, microwaves, and visible light, which is 186 thousand miles per second or 3 million meters per second.
It would take approximately 4.55 seconds for the sound of thunder to travel 1500 meters at a speed of 330 meters per second. This is calculated by dividing the distance by the speed of sound.
1500 meters/330 meters per second = 4.55 seconds
How much time would it take for the sound of thunder to travel 2000 meters if sound travels a speed of 330 meters per sec.
Thunder travels at the speed of sound, which is approximately 1,125 feet per second (343 meters per second) in air at room temperature. The speed of sound can vary depending on temperature and humidity levels in the atmosphere.
In a vacuum, light will travel 299,792,458 meters in one second.
Sound travels, in air, at about 320 meters per second. Light travels about 300 000 000 meters per second
Light travels at 299792458 meters per second in a vacuum.
2191.21 meters per second.
Sound travels at around this speed in air.It's possible that you are thinking of something else that could travel at this speed, but sound was the first thing that I thought of.
Sound travels at approximately 1500 meters per second in water.
A quick rule of thumb is 5 seconds. Since sound travels at a little over 1000 feet per second which is about a fifth of a mile. A better estimate is 1125 feet per second. 5280 / 1125 = 4.693 seconds
Sound travels faster through wood than through water. In wood, sound travels at around 3300 meters per second, while in water it travels at around 1500 meters per second.
