please answer....​

Answer 1

Answer:

1. mirror formula

Explanation:

1 by v + 1 by u minus 1 by f 2magnificiation hi by ho = -vby u

Answer 2

Explanation:

Sign Convention for Spherical Mirror: ... This means sign is always taken as – (negative) in front of a spherical mirror. For example; the distance of object is always taken as – (negative) in case of both types of spherical mirror, i.e. concave and convex mirrors. Sign is taken as + (positive) behind the spherical mirror.

Magnification (m) = h/h

'In a concave mirror, the magnification is the ratio of the height of the image to the height of the object. The magnification is also equal to the negative of the ratio of the distance of the image from the mirror to the distance of the object from the mirror .
