Because distance/time = the speed at which something travels.
A light-minute is a measure of distance, not time. A light-minute is the distance light travels in a vacuum in one minute. Approximately 11,160,000 miles (18,000,000 km)
60 A.S apex :)
(distance the car travels) divided by (time it takes to cover that distance)
Speed = Distance / Time
Light travels approximately 1 micron in 3.3 femtoseconds.
You FIRST see it, then you HEAR it. The time delay depends on your distance from the source of the explosion. The explanation, light travels faster than sound.
Light travels approximately 983,571,056 feet in vacuum in the time it takes sound to travel 1100 feet in air.
"Light year" is a distance. Specifically, it's the distance that light travels through vacuum in one year. The distance is approximately 5,878,291,000,000 miles.
A light-minute is a unit of distance that represents the distance light travels in one minute, which is approximately 18.6 million kilometers.
Sound travels at approximately 343 meters per second in air at room temperature. So, in this scenario, it would take approximately 3 seconds for the sound of the explosion to reach you since you are 1020 meters away.
The mean distance of the Sun from the Earth is approximately 149,600,000 kilometers, or 92,960,000 miles, and its light travels this distance in 8 minutes and 19 seconds
That is short for "light-year" - the distance light travels in a year. Approximately 9.5 million million kilometers.
The distance of the Sun from the Earth is approximately 149,600,000 kilometers, or 92,960,000 miles, and its light travels this distance in 8 minutes and 19 seconds.
An observer sees an explosion before hearing it because light travels much faster than sound. Light travels at approximately 299,792 kilometers per second (about 186,282 miles per second), while sound travels at about 343 meters per second (around 1,125 feet per second) in air. This significant difference in speeds means that the light from the explosion reaches the observer almost instantly, while the sound takes longer to arrive. As a result, there's a noticeable delay between seeing the explosion and hearing it.
The distance that light travels in one day is approximately 93 million miles or 150 million kilometers. This distance is equivalent to 25,902,068,371 miles or 41,715,338,152 kilometers in one day.
Light travels at a speed of approximately 30 centimeters per picosecond in a vacuum.
