How can a spherical xqf+ cbe4(x29fps j)kf 1)iqkv, 2so7- g72za*iwfel xff)i zmirror have a negative object distance?
参考答案:
A spherical mirror can have negative object distance
if some other system of lenses and/or mirrors forms an image that lies behind
the spherical mirror – that is, the image of the other optics lies on the
non-reflecting side of the spherical mirror.
Then, since the object for our spherical mirror is on the back side of
the mirror, the convention is to label this a negative object distance.
