A concave mirror has focal length / . When an object isplaced a distance dQ> f from this mirror, a real image withmagnification m is formed, (a) Show that m = / / ( / - dQ).(ib) Sketch m vs. dQ over the range f < d0 < +oo where/ = 0.45 m. (c) For what value of dQ will the real imagehave the same (lateral) size as the object? (d) To obtain areal image that is much larger than the object, in whatgeneral region should the object be placed relative to themirror?
