from fundamentals of physics 7edQ4
In figure 34-25, stick figure Ostands in front of a spherical mirror that is mounted within the boxed region; the central axis through the mirror is shown. the four stick figures I1 to I4 suggest general locations and orientations for the images that might be produced by the mirror. (the figures are only sketched in; neither their heights nor their distances from the mirror are drawn to scale.) (a) which of the stick figures could not possibly represent images? of the possible images, (b) which would be due to a concave mirror, (c) which would be due to a convex mirror, (d) which would be virtual, and (e) which would involve negative magnification.
In the figure, O is to the left of the mirror. Possible images I1 and I2 are to the left of the mirror, I3 and I4 are to the right. I1 and I3 have the same orientation as O, and I2 and I4 are inverted.
Explanation / Answer
(a) Irrespective of the type of the mirror, stick figures I1 and I4 does not represent the image . Because no mirror forms erect image infront of the mirror and the inverted image behind the mirror. (b) I2 , I3 are due to concave mirrors because concave mirror forms both real and erect images. (c) I3 can be due to a convex mirror because convex mirror forms only vitual image. (d) I3 is virtual because it is behind the mirror and erect . (e) I2 involves negative magnification as the image is inverted with respect to the object .
