Problem

A spherical mirror has a radius of curvature of

40\,\text{cm}

. Where should an object be placed so that a real image forms

30\,\text{cm}

in front of the mirror? (Distances are measured from the mirror along the principal axis.) a)

s_o = 12\,\text{cm}

in front of the mirror b)

s_o = 60\,\text{cm}

in front of the mirror c)

s_o = 50\,\text{cm}

in front of the mirror d)

s_o = -120\,\text{cm}

(behind the mirror)
