Question

More mirrors. Object O stands on the central axis of a spherical or plane mirror. For this situation (The table below. All distances are in centimeters.) , find (a) the radius of curvature r (nonzero number or O if infinity), (b) the image distance i, (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 m R/V I/NI Side Concave +16 (a) Number (b) Number (c) Number Units Units Units cm S This answer has no units o (degrees) kg m/s m/s 2

Explanation / Answer

f = 24 cm

r = 2 X f

= 2 X 24

f = 48 cm

p = + 16 cm

1 / i + 1 / p = 1 / f

1 / i = 1 / 24 - 1 / 16

i = - 48 cm

m = - p / i

m = 16 / 48

m = 0.3333

f   r            p          i             m              R/V I / NI                       side

24     48         +16      - 48         0.333          V                        I    Opposite
