55. The sphere (of radius 0 . 35 m) is a convex mirror with focal length f = 0 . 175 m. We adopt the approximation that the rays are close enough to the central axis for Eq. 35-4 to be applicable. We also take the “1 . 0 m in front of . .. [the] sphere” to mean p =1 . 0 m (measured from the front surface as opposed to being measured from the center-point of the sphere). (a) The equation 1

Unformatted text preview: /p + 1 /i = 1 /f yields i = − . 15 m, which means the image is 15 cm from the front surface, appearing to be inside the sphere. (b) and (c) The lateral magniFcation is m = − i/p which yields m = 0 . 15. Therefore, the image distance is (0 . 15)(2 . 0 m) = 0 . 30 m; that this is a positive value implies the image is erect (upright)....
