Lens equation:

1f=1so+1si

Magnification:

m=hiho=-siso

(a)

Solve for si:

si = (1/f - 1/so)-1 = ((so - f)/f•so)-1 = fso/(so - f)

Problem Details

A candle (ho = 0.39 m) is placed to the left of a diverging lens (f = -0.054 m). The candle is so = 0.34 m to the left of the lens.

ho = 0.39 m
f = -0.054 m
so = 0.34 m

Part (a) Write an expression for the image distance, si.

Part (b) Numerically, what is the image distance in meters?

Part (c) Is this real or virtual?

Part (d) Numerically, what is the image height, hi?
