The magnification produced by a plane mirror is +1.What does this mean
Answers
The magnification produced by a plane mirror is +1 means then the size of the image is equal to the size of the object. If m has a magnitude greater than 1 the image is larger than the object, and an m with a magnitude less than 1 means the image is smaller than the object.
Answer :
Magnification is the measure that indicates the size of the image with respect to the size of the object.
Magnification is represented by "m".
The magnification produced by a plane mirror is called linear magnification.
The measure of magnification produced by plane mirror is + 1.
Its magnification is 1 because the the size of the object is equal to the size of the image.
The positive sign in the magnification of the plane mirror indicates that the image is is erect and virtual, just like the object.
Magnification in Mirrors :
The formula for finding the magnification in both convex and concave mirror is : m = -v/u = h'/h.
Magnification in Lenses :
The formula for finding the magnification in both convex and concave lenses is : v/u = h'/h.
Here,
v is the image distance.
u is the object distance.
h' is the Image height.
h is the object height.
