Can you see the past if you put a mirror in space?
Can you see the past if you put a mirror in space?
Yes, we always look into the past, when looking somewhere. There is for instance a mirror on the moon. When sending a laser beam to that mirror, we can detect the reflected light about 2.5 seconds later.
Why do we see the past when we look into space?
The time it takes for light from objects in space to reach Earth means that when we look at planets, stars and galaxies, we’re actually peering back in time. Every time we look at something ‘up there’ we’re seeing it as it was in the past. …

Do mirrors reflect everything in front of them?
Mirrors reflecting other mirrors A mirror reflects everything in front of it including another mirror. If you place two mirrors at an angle, you increase the number of reflected images you can see. Depending on the angle you choose, you can see a number of unbroken reflections and one or more composite or partial reflections.
How do you get the image of the object behind the mirror?
By forming images of all points of the object, we obtain an upright image of the object behind the mirror. Two light rays originating from point P on an object are reflected by a flat mirror into the eye of an observer. The reflected rays are obtained by using the law of reflection.
