Final answer:
It takes approximately 1.33 seconds for light to travel the distance from the Moon to the Earth, calculated by dividing the distance of 400,000 km by the speed of light, which is 300,000 km/s.
Step-by-step explanation:
The question asks how long it takes for light to travel from the Moon to the Earth. Given the distance from the Moon to Earth is 400,000 km and the speed of light is 300,000 km/s, one can calculate the time it takes for light to travel this distance by dividing the distance by the speed of light. The calculation is as follows:
Time = Distance / Speed of Light
Time = 400,000 km / 300,000 km/s
Time = 1.33 seconds
Therefore, it takes approximately 1.33 seconds for light to travel from the Moon to the Earth. This time delay can be observed, for instance, when there is a lag in communication between astronauts on the Moon and Mission Control on Earth.
The distance between the Moon and Earth is 400,000 km. The speed of light is 300,000 km/s. To calculate how long it takes light to travel from the Moon to Earth, we divide the distance by the speed of light:
Time = Distance / Speed = 400,000 km / 300,000 km/s = 1.33 seconds.
Therefore, it takes approximately 1.33 seconds for light to travel from the Moon to Earth.
