Question

Chapter 34, Problem 010 Spherical mirrors. Object O stands on the central axis of a spherical mirror. For this situation object distance is Ps+18 cm, the type of mirror is concave, and then the distance between the focal point and the mirror is 11 cm (without proper sign). Find (a) the radius of curvature r (including sign), (b) the image distance i, and (c) the lateral magnification m. Also, determine whether the image is (d) real or virtual, (e) inverted from object O or noninverted, and (f) on the same side of the mirror as O or on the opposite side. (a) Number (b) Number (c) Number Units Units Units

Explanation / Answer

A). Radius of curvature = 2.f = 22cm

B).1/ Image distance = (1/11)+(1/18) = 29/198

Image distance = 6.82 cm

C). M = -(v/u) = 6.82/18 = 0.378

D).image is virtual and inverted and diminished

Same side of the mirror.
