An object 5 millimeters high is located 15 millimeters in front of a plane mirror. How far from the mirror is the image located? answer 15 millimeters.
The image is the same distance behind the mirror as the object is in front of the mirror.
noooo i am too dub *dumb

D. 8 millimeters
To understand why the image is located 15 millimeters behind the mirror, we need to apply the concept of reflection in a plane mirror.
When light rays from an object reach a mirror, they bounce off the mirror surface and create reflected rays. According to the law of reflection, these reflected rays travel in such a way that the angle of incidence is equal to the angle of reflection, and the object distance is equal to the image distance.
In this case, the object is located 15 millimeters in front of the mirror. The light rays traveling from the object will hit the mirror's surface and reflect back. Since the object is located in front of the mirror, the image will appear behind the mirror.
Since the object distance is given as 15 millimeters, the image distance from the mirror will also be 15 millimeters. Therefore, the image is located 15 millimeters from the mirror.
It's important to note that in a plane mirror, the image formed is virtual, upright, and the same size as the object.
