Regardless of which side of the mirror you designate as the positive side,
one of them is positive and the other one is negative, since the object and
image are always on opposite sides of the mirror.
BTW ... If the mirror is flat, then their absolute values are equal.
For a flat mirror (front surface) with the object having an angle of incidence with the mirror of 45 degrees, and the image measured perpendicular to the object, the speed is v. A side note, using a laser pointer, a spinning mirror, a meter stick, a ruler, and a sheet of paper, and measured, with a lab partner, the speed of light within 10%, in the space of a square meter. This was so many years ago, that the speed of light was much less than it is today.
Put a mirror in front of it.
Mirror reflects light from an object and that means that it reflects light from the right side of an object to the right side of a mirror and light form the left side of an object to the left side of a mirror. The picture that is created in a mirror is actually a reflection of an object that is in front of a mirror and therefore it looks reverse.
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.
Characteristics of an image formed by the plane mirror are :- * Virtual and erect (up right ) . * The image is of same size as that of the object . *The image is far behind the mirror as the object is in front of it . *The image is laterally inverted .

real reflection of the object in front of it at a time.
The same speed: the image will always appear to be at a point exactly behind the mirror as the object is in front.
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.
Your brain perceives the reflected object as being as far BEHIND the mirror as the real object is in FRONT of the mirror.
light bounces off an object and on to the miorror surface where it is then reflected at the same wavelength as it was casted on to there with
