Problem: 1.) Find the position of the final image of the 1.0-cm-tall object2.) Find the size of the final image of the 1.0-cm-tall object3.) Is the object inverted or erect?

FREE Expert Solution

Lens equation:

1f=1so+1si

Magnification:

m=hiho=-siso

(1.) 

For the convex lens:

f = 5.0 cm

so = 4.0 cm

si = (sof)/(so - f) = (4.0 × 5.0)/(4.0 - 5.0) = -20 cm

For the concave lens:

f' = - 8 cm
