Question

Suppose you have a three concave mirror a, b and c for cfocal focal length 10 cm 15 CM and 20 CM 2concave mirror you perform the experi
ment of image formed formation formation of three value of object distance of 10 cm, 20 cm and 30 cm given a reason answer the following for the three object distance identify the mirror which will form an image of money fraction

Answer 1

The mirror equation is 1v+1u=1f, where v,u and f are the distances of the image and object from the mirror and the focal length respectively.

Magnification, M=hiho=−vu, where hi and ho are the heights of the image and object respectively.

As per the new Cartesian convention, distances from the mirror toward the side of the object are negative and distance toward the other side are positive. Distances above the principal axis are positive and distances below the principal axis are negative.
