This would result in a top speed of 12.75 meters per second, or 28.53mph – and a new world record of 9.27 seconds. There is a pause between steps of about 50 microseconds. How fast is a lightning? At 5-foot-11 and 130 pounds, she was lightning fast. Follow LiveScience @livescience . Thunder is the vibration that is emitted by the rapid expansion and contraction of air. Wilma watchers in the late 1950s and early '60s were admonished: don't blink. Speed of sound: 340 m/s or 0.21 mi/s. I know superman can go at least Mach 4, Which is 4 times the speed of sound(4 * 330 = 1320 meters / second)1320 m/s = 2953 mph Can Flash run faster How can I tell how far I am from the lightning? The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. It is symbolized as mps or m/s. The speed of light in vacuum is:186,282 miles per second.299,792,458 meters per second. Meters per second is a metric system speed unit to express the number of meters covered in one second. A flash preceding thunder by five seconds would indicate a distance of approximately 1.7 km or 1.1 mi (5 × 343 m). From these two entries you will have your results expressed in a number of forms. Like other forms of light, the light emitted from the lightning travels near the speed of light. How to convert m/s to ft/s? See the example on the next page. 1 Meter per second (m/s) is equal to 3.28084 feet per second (ft/s). A three-second count, then, would place the lightning strike about 1,020 m away, or roughly 1 km. There is also a special table for the track and field athlete. Speed of light: 3 x 108 meters per second (m/s) or 2 x 105 miles per second (mi/s). LIGHTNING OVERVIEW - PHENOMENON TRUE Lightning is the flash of light that occurs when charge separation occurs. To convert meters per second to feet per second, multiply the meters per second value by 3.28084. These sparks travel at speeds that are fast even for lightning—around 10 to 100 million meters per second—and produce very powerful radiofrequency (RF) radiation as high as … After you see lightning, count the number of seconds until you hear thunder. A lightning flash preceding its thunder by one second would be approximately 343 m (1,125 ft) in distance; a delay of three seconds would indicate a distance of about 1 km or 0.62 mi (3 × 343 m). You will have distance per time such as kilometres per hour or metres per second. You will also have time taken to travel certain distances such as seconds per metre or seconds per 100 meters. Follow Elizabeth Palermo on Twitter @ techEpalermo . This speed is near 300,000,000 meters per second. Lightening travels at a blazing 186,000 miles (299,000 kilometers) per second. The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics.Its exact value is defined as 299 792 458 metres per second (approximately 300 000 km/s, or 186 000 mi/s).It is exact because, by international agreement, a metre is defined as the length of the path travelled by light in vacuum during a time interval of 1 ⁄ 299 792 458 second. The "leader", the first stroke of a lightning discharge, actually proceeds in steps -- lengthening by about 30 meters at a time, taking about a microsecond (one millionth of a second) to do each step.
