What is the sign for object and image distances that are measured on the front side of a mirror?

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.

What is the speed of the image if an object is fixed in front of a plane mirror and the mirror is moved with a speed v?
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.
How can you create mirror image of a given object?
Put a mirror in front of it.
Why does a mirror show everything in reverse?
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.
Where does your image appear to be when you look into a plane 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.
What are the 5 Properties of an image in a plane mirror?
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 .

An object is kept in front of a concave mirror of focal length 20cm the image is 3 times the size of the object calculate 2 possible diastances of the object from the mirror?
40cm

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.
How can you describe a plane mirror?
real reflection of the object in front of it at a time.
What will be the speed of image if object moves towards plain mirror?
The same speed: the image will always appear to be at a point exactly behind the mirror as the object is in front.
If an object 5 millimeters high is located 15 millimeters in front of a plane mirror How far from the mirror is the image located?
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.
How does the human brain perceive the position of the image seen on plane mirrors?
Your brain perceives the reflected object as being as far BEHIND the mirror as the real object is in FRONT of the mirror.
Why the object appear when you put the object in front of 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

An object is 5 millimeters high is located 15 millimeters in front of a plane mirror how far from the mirror is the image located?
30 millimeters
