Question

m =-1 signifies what will the image formed

Answer 1

▬▬▬▬▬▬▬▬▬▬▬▬

Magnification(M) = -1

The magnification is negative, so the image that will be formed will be real and inverted.

Formula of finding magnification :-

$\displaystyle{\sf{\frac{h_i}{h_o} }}$

♣ For mirror,

$\displaystyle{\sf{\frac{-v}{u} }}$

♣ For lens,

$\displaystyle{\sf{\frac{v}{u} }}$

Answer 2

m = hight of image/hight of object and if m is -1 means hight of image and hight of object is equal in hight but - sign show image is inverted image and when object place on center of curvature (C) then image also form on C
