The speed of light is approximately 299,800 kilometers per second (km/s), and the average distance from the Earth to the Moon is about 384,400 kilometers. To find out how long it takes for light to travel this distance, we can use the formula:
Time = Distance / Speed
Plugging in the values, we have:
Time = 384,400 km / 299,800 km/s
This calculation gives us:
Time ≈ 1.28 seconds
So, it takes light roughly 1.28 seconds to travel from the Earth to the Moon. This interval is quite short, highlighting just how fast light travels across the vastness of space!
