Image formed by a plane mirror is (a) virtual, behind the mirror and enlarged. (b) virtual, behind the mirror

(a) concave mirror (b) convex lens (c) concave lens (d) convex mirror

(d) When an object is placed between the pole and principal focus of a concave mirror, the image formed is virtual, erect, and larger than the object.

Concave mirror can give an erect and enlarged image of an object, when object is placed between pole and focus of the mirror.

Here, in case of concave mirror u=10 cm [u, is always negative] v =?;m = - 3 [real image] Now the magnification formula is m= -v/u or -3= -(v/-10) or , v = -30 cm. Image will...

The image formed by a concave mirror is virtual, erect and larger only when the object is placed between the pole of the mirror and its principal focus. So correct...

The virtual image formed by a concave mirror is always magnified whereas the virtual image formed by a convex mirror is diminished.

(b) only a concave mirror.

(iii) 6 m Explanation: As David moves 1 m towards the mirror, the image also moves 1 m towards the mirror. Now the distance between David and mirror is 3 m and...

(a) Virtual image formed is larger in size in case of concave mirror.

(b) The image formed by objective lens of compound microscope is real and enlarged, while final image formed by compound microscope is inverted, virtual, enlarged and at a distance D...
