Answer:
A larger image is produced when >
A smaller image is produced when <
An upright image is produced when m is positive
An upright image is produced when m is negative
Explanation:
The mirror equation is given as follows;
For concave mirrors, f = focal length
= Image distance from the mirror (-ve = Image is behind the mirror +ve = Image is in front of the mirror)
= Object distance from the mirror (-ve = Object is behind the mirror +ve = Object is in front of the mirror)
m = Magnification (-ve m = Inverted image +ve m = upright image)
= Image height
= Object height
f = Focal length of the mirror
To produce a larger image >
To produce a smaller image <
To produce an upright image, m should be positive hence, will be negative or the image will appear behind the mirror
To produce an inverted image, m should be negative hence, will be positive or the image will form in front of the mirror.
