Question

Between which 2 parts of a concave mirror an object to be placed to obtain a magnification of -3 ?

Answer 1

Answer:

Object should be place between Center of curvature (C) and Focal point (F)

Explanation:

When we place object between C and F

=> we get image beyond C

=> real and inverted

=> magnified (enlarged) image

so here in question they gave magnification = -3

m = -ve sign represents real image

m = 3 means m > 1 --- enlarged image
