Question

A converging lens (f1 = 24.0 cm) is located 56.0 cm to the left of a diverging lens (f2 = -28.0 cm). An object is placed to the left of the converging lens, and the final image produced by the two-lens combination lies 21.1 cm to the left of the diverging lens. How far is the object from the converging lens?

Answer #1

A converging lens (f1 = 24.0 cm) is located
56.0 cm to the left of a diverging lens (f2 =
−28.0 cm). An object is placed to the left of the converging lens,
and the final image produced by the two-lens combination lies 22.1
cm to the left of the diverging lens. How far is the object from
the converging lens?

A converging lens (f1 = 24.0 cm) is located 56.0 cm to the left
of a diverging lens (f2 = -28.0 cm). An object is placed to the
left of the converging lens, and the final image produced by the
two-lens combination lies 19.4 cm to the left of the diverging
lens. How far is the object from the converging lens?

A converging lens (f1 = 24.0 cm) is located 56.0 cm to the left
of a diverging lens (f2 = -28.0 cm). An object is placed to the
left of the converging lens, and the final image produced by the
two-lens combination lies 20.0 cm to the left of the diverging
lens. How far is the object from the converging lens?

A converging lens (f1 = 24.0 cm) is located
56.0 cm to the left of a diverging lens (f2 =
-28.0 cm). An object is placed to the left of the converging lens,
and the final image produced by the two-lens combination lies 20.7
cm to the left of the diverging lens. How far is the object from
the converging lens (including units)?

A converging lens (f1 = 22.0 cm) is located 43.0 cm
to the left of a diverging lens (f2 = -26.0 cm). An
object is placed 38.0 cm to the left of the converging lens.
Relative to the diverging lens, where is the final image
located?
Is it real or virtual?
How does the size of the image compare to the size of the
object?

A converging lens (f1 = 12.7 cm) is located 30.6 cm
to the left of a diverging lens (f2 = -6.48 cm). A
postage stamp is placed 33.9 cm to the left of the converging lens.
Locate the final image of the stamp relative to the diverging
lens.

A converging lens (f = 11.3 cm) is located 24.0 cm to
the left of a diverging lens (f = -5.42 cm). A postage
stamp is placed 46.0 cm to the left of the converging lens.
(a) Locate the final image of the stamp relative
to the diverging lens. (b) Find the overall
magnification.

A converging lens (f1 = 11.9 cm) is located 27.6 cm
to the left of a diverging lens (f2 = -5.94 cm). A
postage stamp is placed 34.8 cm to the left of the converging lens.
Find the overall magnification.

A diverging lens (f1 = −13.0 cm) is located 25.0 cm
to the left of a converging lens (f2 = 22.5 cm). A
3.5-cm-tall object stands to the left of the diverging lens,
exactly at its focal point. What is the height of the final image
(including proper algebraic sign)?

8.A diverging lens (f1 = −10.5 cm) is located 43.0 cm to the
left of a converging lens (f2 = 23.5 cm). A 3.0-cm-tall object
stands to the left of the diverging lens, exactly at its focal
point. Determine the distance of the final image relative to the
converging lens (including proper algebraic sign
