same distance
The answer is 15 millimeters behind the mirror, and the distance from the actual object to the image is 30 millimeters. Plane mirrors have a flat focus that places the image as far behind the mirror as you are in front of it.
Since the mirror reflects the image in front of it, the apparent distance of oneself standing in the mirror will be twice as far as the distance from you to the mirror. If you are standing 2 meters from the mirror, the image will appear as 4 meters away.
A mirror is formed by a glass plate with a reflective coating behind it. A mirror reflects the right that hits it, thereby forming an image of what is in front of the mirror.
Absolute value is related to distance because distance is not a signed quantity. For instance, if you were 100 metres in front of something, your distance to it would be 100 metres. If you were 100 metres behind it, your distance to it would still be 100 metres, not -100 metres.
Usually as we say the details of the image we point out their, size, position, type and nature. In case of plane mirror, size = same size of the object position = at the same distance as the object is in front of the mirror type - erect one nature - virtual image. This means could be seen but not be caught on a screen.
It's equal. The way the light reflects means that you end up the same distance away from it as you are reflected in it. That's if what I remember from Physics lessons is true :P Hope this helps :)
mirage mirror it's self!
The image seen in a plane mirror appears to be the same distance behind the mirror as the object is in front of it. This is because light rays reflect off the mirror and create a virtual image that appears behind the mirror at the same distance.
The distance from the object to the mirror is equal to the distance from the image to the mirror in a plane mirror. The image appears to be as far behind the mirror as the object is in front of it, so the apparent distance from the image to the mirror is equal to the actual distance from the object to the mirror.
It's a virtual reflection of the object which appears as an image as much behind the mirror as the distance of the object in front.
For a flat mirror, the object distance is equal to the image distance. This means that the image formed by a flat mirror is the same distance behind the mirror as the object is in front of it.
plane mirror. The image location will be the same distance behind the mirror as the object's distance in front of the mirror.
I can see my reflection in the mirror, which is an image of my face, located behind the mirror's surface. The image appears to be at the same distance behind the mirror as my actual face is in front of the mirror.
The image will be located the same distance behind the mirror as the object is in front of it, so the image will be 15 millimeters behind the mirror.
The image formed by a plane mirror is virtual, erect, same size as object, and laterally inverted ( left side appears right and right side appears left ). Also, the virtual image is as far behind the mirror as the object is in front of the mirror.
In a plane mirror, the image distance (di) is equal to the object distance (do). The image formed is virtual, upright, and the same size as the object, and it appears behind the mirror at the same distance as the object in front of the mirror.
The image produced by a plane mirror will be virtual, upright, and the same size as the object. It will appear to be the same distance behind the mirror as the object is in front of it.
