The time it takes for sunlight to reach us from the Moon depends on the distance between the Moon and Earth. On average, the distance from the Moon to Earth is about 384,400 kilometers (238,900 miles).
The speed of light in a vacuum is approximately 299,792 kilometers per second (186,282 miles per second). Using these values, we can calculate the time it takes for light to travel from the Moon to Earth.
To calculate the time, we divide the distance between the Moon and Earth by the speed of light:
Time = Distance / Speed
Time = 384,400 km / 299,792 km/s
This calculation gives us an approximate time of 1.28 seconds for sunlight reflected off the Moon to reach us on Earth.
It's important to note that this calculation assumes a straight-line distance between the Moon and Earth and doesn't account for factors such as the curvature of space or the orbital dynamics of the Earth and Moon. However, for practical purposes, this approximation is accurate enough to estimate the time it takes for reflected sunlight to reach us.
