Barbara places an object in front of a mirror. The mirror produces an image that is inverted, real, and smaller than the object.Which kind(s) of mirror could Barbara be using?
A
convex, because concave and plane mirrors produce only virtual imagesB
concave, because plane and convex mirrors produce only upright virtual imagesC
concave or convex, because both types of mirrors produce images that are inverted and realD
convex or plane, because both types of mirrors produce an image that is smaller than the object5

upright, smaller than object, virtualC
inverted, same size as object, realD
upright, same size as object, virtual8

Jessie draws a ray diagram to show how an image of a candle is produced by a concave mirror when the candle is placed in front of the center of curvature. Jessie thinks the image should be virtual and behind the mirror.Which best describes Jessie’s error?
A
The object should be placed anywhere on the principal axis.B
The object should be at the center of the curvature.C
The object should be between the center and vertex.D
The object should be between the focal point and vertex.Did you find these answers helpful?
