(4) d and a
(1) a and b
(25 b and c

Answer 1

Step-by-step explanation:

Magnification of a concave lens or a convex mirror is always positive because they always form virtual and erect images. It can be negative or positive for a convex lens or a concave mirror.

Positive magnification for virtual images and negative magnification for real images is true only when a single optical device is used. When used as a combination, a virtual and inverted image may be formed. One such example is a compound microscope

Answer 2

Answer:

formula for magnification of spherical mirror

=

$\frac{height \: of \: image}{height \: of \: object} = - \frac{v}{u}$
