Question

Spherical mirrors, object O stands on the central axis of a spherical mirror, for this situation object distance is rho_s = +19 cm, the type of mirror is concave, and then the distance between the focal point and the mirror is 13 cm (without proper sign). Find (a) the of curvature r (including sign), (b) the image distance i_1 and (c) the lateral magnification m. Also, determine whether the image is (d) real 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 units (b) Number units (c) Number units

Explanation / Answer

p = 19 cm

f = 13 cm

(A) R= 2f = 26 cm

(B) 1/f = 1/p + 1/q

1/13 = 1/26 + 1/q

q = 26 cm

(c) m = - q / p = - 1

(D) q is +ve hence image will be real.

(E) m < 0

inverted.

(f) on the same side.
