Question

Shown in the figure below is a system containing two lenses and an object. The focal lengths of the two lenses are f₁ = -19 cm and f₂ = 9.5 cm. The two lengths indicated in the figure are L₁ = 28.5 cm and L₂ = 15.2 cm.

Determine all the following about the image from the first lens only:
Object distance for the first lens, d₀₁.  cm
Image distance for the first lens, d_i1.  cm
Magnification of the first lens, m₁.

The second lens uses the image from the first lens as its object. Determine all the following about the image from the second lens:
Object distance for the second lens, d₀₁.  cm
Image distance for the second lens, d_i1.  cm
