Question

Chapter 34, Problem 029 More mirrors. Object O stands on the central axis of a spherical or plane mirror. For this situation (see the table below, all distances are in centimeters; the given value of image distance is a magnitude with unknown sign), find (a) the focal distance f, (b) the object distance p, (c) the lateral magnification m, whether (d) the image is real or virtual, (e) inverted or noninverted from o, and (f) on the same side of the mirror as object O or on the opposite side Type rPm R/V /NI Side Convex -52 5.1 (a) Number (b) Number (c) Number Units Units Units

Explanation / Answer

Focal distance = r/2 =-26 cm

Object distance = 1/((1/5.1)+(1/26)) = 4.273cm

Lateral magnification =-(v/u) = -(5.1÷(-4.273)) = 1.193

Image is virtual and enlarged.
