Where is the object placed in a compound microscope?

An object is placed $15\, cm$ from a convex mirror of radius of curvature $60\, cm$. Find the position of the image and its magnification.

$A$ ray of light passing through the principal focus of a concave mirror,after reflection,travels in which direction?

Which of the following can produce a magnification of $+5$ as well as $-5$?

At what position should an object be placed in front of a concave mirror to obtain a magnification of $(- 2)$?

An object is placed at the following distances from a concave mirror of focal length $15 \, cm$.
$(a)$ $10 \, cm$ $(b)$ $20 \, cm$ $(c)$ $30 \, cm$ $(d)$ $40 \, cm$
Which position of the object will produce:
$(1)$ Virtual image
$(2)$ $A$ diminished real image
$(3)$ An enlarged real image
$(4)$ An image of same size
