Hint: If the image is beyond the C the image will be considered as inverted and enlarged. Concave mirror makes the object taller and wider because such mirrors are bent inward.
Step By Step Answer:
We know that linear magnification of a convex mirror is always positive the given magnification is negative so,
The list of four information obtain from this statement about the mirror/image are given below:
a.)It is a concave mirror
b.)Image is inverted
c.)Image is real
d.)As magnification=-3, as we can see it is greater than one so the image is enlarged.
THERE ARE 6 POSSIBILITIES OF POSITION OF OBJECT IN CONCAVE MIRROR:
a.)The object at infinity.
b.)The object is placed between infinity and centre of curvature (C)
c.)The object is placed at the centre of curvature(C)
d.)The object between centre of curvature(C) and the principal of focus
e.)The object at principle of focus (F)
f.)The object between principle of focus(F) and the pole(P)
Note: Don’t get confused with concave mirror and concave lens they both are different in their own ways; concave mirror has the ability to form both real and inverted images of various sizes and virtual depending on the position of object whereas a concave lens has the ability to form the only virtual, diminished and erect images for all positions of the object.
