In the year 1178, five monks at Canterbury Cathedral in England observed what appeared to be an asteroid colliding with the moon, causing a red glow in and around it. It is hypothesized that this event created the crater Giordano Bruno, which is right on the edge of the area we can usually see from Earth.

In the year 1178, five monks at Canterbury Cathedral in England observed what appeared to be an asteroid colliding with the moon, causing a red glow in and around it. It is hypothesized that this event created the crater Giordano Bruno, which is right on the edge of the area we can usually see from Earth.

How long after the asteroid hit the Moon,which is away ,would the light first arrive on the earth in seconds

The time it would take is  

Explanation:

The objective of this question is to obtain the time the light would arrive earth

      We are told that the distance from moon to  earth is  

Now generally time is mathematically represented as

The c here is the speed of light which has a value of

        Now substituting values

Incomplete question: The question is: How logn after the asteroid hit the Moon, which is 3.84x10⁵km away, would the light first arrive on Earth in seconds?

The answer is 1.28 s

Explanation:

Data given:

d = distance = 3.84x10⁵km = 3.84x10⁸m

v = velocity of light = 3x10⁸ m/s

The time will be:

i was thinking more like reflects green light, just not sure
