Question

A 2.05-cm-tall object is placed 30.0 cm to the left of
a converging lens with a focal length f1 = 21.0 cm . A diverging
lens, with a focal length f2 = -42.5 cm , is placed 30.0 cm to the
right of the first lens.

How tall is the final image of the object?________cm

Answer #1

A 2.05-cm-tall object is placed 30.0 cm to the left of a
converging lens with a focal length f1 = 20.5 cm . A diverging
lens, with a focal length f2 = -42.5 cm , is placed 30.0 cm to the
right of the first lens.
Q:How tall is the final image of the object?

A 2.05-cm-tall object is placed 30.0 cm to the left of a
converging lens with a focal length f1 = 20.0 cm . A diverging
lens, with a focal length f2 = -50.0 cm , is placed 30.0 cm to the
right of the first lens. You may want to review (Pages 959 - 966) .
How tall is the final image of the object?

A 1.8 cm tall object is placed 5 cm to the left of a converging
lens (lens #1) with a focal length of 1.3 cm. To the right of this
converging lens is a diverging lens (lens #2) that has a focal
length of 2.6 cm. The diverging lens is placed 22.4 cm from the
converging lens. Where is the final image, is it real or virtual,
and is it upright or inverted?

1.Light with a wavelength of 626 nm passes through a slit 7.74
μm wide and falls on a screen 1.75 m away. Find the linear
distance on the screen from the central bright fringe to the first
bright fringe above it._________cm

An
object is placed 30 cm to the left of a converging lens of focal
length 10 cm. A diverging lens of focal length -15 cm is 20 cm to
the right of the converging lens.

the first lens?
b) Is it real or virtual?
c) Where is the final image relative to the second lens?

A converging lens of focal length f1 = +22.5 cm is placed at a
distance d = 60.0 cm to the left of a diverging lens of focal
length f2 = −30.0 cm. An object is placed on the common optical
axis of the two lenses with its base 45.0 cm to the left of the
converging lens. (The thin-lens approximation may be assumed to
hold.) (a) Calculate the location of the final image and its
overall magnification with respect...

An object 2.00 cm high is placed 31.1 cm to the left of a
converging lens having a focal length of 26.1 cm. A diverging lens
having a focal length of −20.0 cm is placed 110 cm to the right of
the converging lens. (Use the correct sign conventions for the
following answers.)
(a) Determine the final position and magnification of the final
image. (Give the final position as the image distance from the
second lens.)

final position in...

9. A diverging lens (f1 = −11.0 cm) is located 21.0 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. What is the height of the final image (including proper
algebraic sign)? cm

A converging lens and a diverging lens, separated by a distance
of 30.0 cm, are used in combination. The converging lens has a
focal length of 15.2 cm. The diverging lens is of unknown focal
length. An object is placed 19.3 cm in front of the converging
lens; the final image is virtual and is formed 12.0 cm in front of
the diverging lens. What is the focal length of the diverging
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 22.1
cm to the left of the diverging lens. How far is the object from
the converging lens?
