Question

a 15.0cm tall object is placed 8.00cm in front of a convex mirror. The mirror has a radius of curvature of -24.0cm. What is the magnification? I got -45 is this right? If not please show a 15.0cm tall object is placed 8.00cm in front of a convex mirror. The mirror has a radius of curvature of -24.0cm. What is the magnification? I got -45 is this right?

Explanation / Answer

using the mirror equation

1/f = 1u + 1/v

f = R/2 = -12 cm

u = 8 cm

1/v = 1/f - 1/u

v = fu/(u - f)

v = -12*8/(8 - (-12))

v = -4.8 cm

Magnification = -v/u

M = -(-4.8)/8 = 0.6
