Question

Explain mirror formula and its magnification, Write down the sign conversation for reflection by Spherical mirror ? ​

Answer 1

Answer:

a formula which gives relation between image distance(v), object distance(u) and focal length(f).

1\V + 1\U =1\f

hope it will help u

Answer 2

HEY FRIEND HERE IS UR ANSWER

Sign convention for reflection by spherical mirror is New Cartesian sign Conention.

The object is placed left of the mirror.The light falls on LHS.

All distances parallel to principal axis are measured from pole of the mirror

All origin RHS ( x-axis) are taken as positive while on LHS origin (x-axis) are taken as negative.

Distance measured perpendicular to above principal axis (y-axis) are positive.

Distance below principal axis perpendicular (y-axis) are negative.

The mirror formula for reflection -

1/v +1/u =1/f

Magnification is for nature of image and size of an object.

m = height of image / height of object .

m=h*/h. or -v/u
