(i) Define the term magnificatio. Write the formula for magnification of mirror explanning the symbols used in the formula.
(ii) The magnification produced by a convex lens is -2. What is meant by this statement and also write the information regarding image obtained from it.

Explanation

(i) Ratio of height of the image to height of the object is magnification.
M(mirror) `=h^(1)//h=-v//u`
h= Height of object
`h^(1)=` Height of image
v=image of distance
u= Object distance
(ii) It means image formed is two times of size of object and the image formed is inverted, formed in front of the lens.
