My Notes Ask Your Teach Two identical diverging lenses are separated b.docx

My Notes Ask Your Teach Two identical diverging lenses are separated by 17 cm. The focal length of each lens is -8.0 cm. An object is located 4.0 cm to the Ie left of the lens that is on the left. Determine the final image distance relative to th Additional Materials ASection 26.9
Solution
here,
the sepration , d = 17 cm
for the first lens
focal length , f1 = -8 cm
object distance , do1 = 4 cm
let the image distance be di1
1/f1 = 1/di1 + 1/do1
- 1/8 = 1/di1 + 1/4
solving for di1
di1 = - 2.67 cm
for the seccond lens
focal length , f2 = -8 cm
object distance , do2 = 19.67 cm
let the image distance be di2
1/f2 = 1/di2 + 1/do2
- 1/8 = 1/di2 + 1/19.67
solving for di2
di2 = - 5.69 cm
