If a concave mirror prayog2nav/1m 9;cye-.r xpesx )z 1n/,gys c b/2r8p* i txnacjl-zdx v 9765yjoduces a real image, is the image necessarily inverted? Expla*ctx 8l di 6p7aj29-vxnyzrj 5in.
参考答案: Yes. When a concave mirror produces a real image
of a real object, this means $d_i$ and
$d_o$ are positive. The magnification
equation (m = $-d_i/d_0$) then says that m is negative, which means the image is
inverted. (If a virtual object is used,
though, to make a real image, then $d_o$
is negative and $d_i$ is positive,
which would give us a positive m and
an upright image.)
