Question

what is meant by arial magnification and linear magnification?

Answer 1

Magnification is basically an enlargement ratio between the image of an object and the object itself.
Linear magnification is calculated for line objects.
When one calculates the area of the image and area of the object, one can call it as arial magnification. But usually in physics, we define
Linear magnfication, angular magnification and axial magnification for line, two dimensional and three dimensional objects.
