Homework Statement
A galileibinocular consists of two lenses with ƒobjective = +30 cm and ƒokular = -10 cm. The distance between the lenses is 30 cm and the binocular is aimed at an object 90 cm away from the objective lens.
Where is the image of the object seen through the binoculars? (the binoculars are not in their normal position)
Homework Equations
1/a1 + 1/b1 = 1/ƒobjective
1/a2 + 1/b2 = 1/ƒokular
L = ƒobjective + ƒokular
The Attempt at a Solution
I started by:
[/B]
1/(90 cm) + 1/b1 = 1/(30 cm) which gave me b1 = 45 cm that is the image that the objective generates. Now I need to do the same for the okular but I don't know how to get a2.
