Question

Consider a convex lens with a focal length of 5.00 cm. An object is located at 12.50 cm. The object is 5.50 cm tall. Draw the ray diagram to scale. Determine the image distance, the height of the image, the magnification and the characteristices of the image.

Answer #1

A convex lens with a focal length of magnitude 4.0 cm and a
concave lens with a focal length of magnitude 10 cm are separated
by a distance of 18 cm as shown in the diagram below. The convex
lens is on the left, and the concave lens is on the right. An
object is then placed 6.0 cm to the left of the convex lens.
Locate the final image. State the distance of the final image
to the right...

A 3 cm. "tall" object is placed 25 cm. from a convex lens with a
focal length of 50 cm. Determine at what distance a focused image
will appear. Determine the height of this image. Create a sketch
(ray diagram) showing the scenario described above labeled as “A”
and a scenario where everything is the same except the focal length
of the lens is changed to 12.5 cm.

A 2.00-cm-tall object is located 18.0 cm in front of a
converging lens with a focal length of 30.0 cm. (a) Use the lens
equation and (b) a ray diagram to describe the type, location, and
height of the image that is formed.

An object is located to the left of a convex lens whose focal
length is 39 cm . The magnification produced by the lens is
m1 = 3.1. To increase the magnification to 4.5, should the
object be moved closer to the lens or farther away? Calculate the
distance through which the object should be moved.

a convex mirror has a focal length of -20 cm.
a. determine an object location for which the image will be one
half the size of the object
b. draw a ray diagram for this situation
c. the mirror is replaced with a thin lens in exactly the same
position. the image and object do not move. find the focal length
of this thin lens.

An object is placed 4 cm away from a concave lens of focal
length 3 cm. A convex lens of focal length 5 cm is placed 4 cm away
from the concave lens in the same direction (so the distance
between convex lens and the object is 8 cm). Use any method to
figure out if the final image is real/virtual, upright/inverted and
find its distance from the convex lens.
Explain in thorough detail.

An object is held 82.7 cm away from a lens. The lens has
a focal length of -31 cm.
A.) Determine the image distance
B.) Determine the magnification.
C.) If the object is 4 cm long, determine the image
height
D.) Which of the following are true about the
image?
The image is virtual
the image is upright
the image is inverted
the image is real
E) Which is true about the lens?
The lens is concave
the lens is...

An object 6 cm high is placed 12 cm in front of a 4 cm focal
length convex lens.
(a) Draw a ray diagram to produce an image.
(b) Calculate the image location and magnification using the
lens equation.
(c) How close is your image position and height to your
calculated value (% difference)?

4. An object is 10.0 cm to the left of a converging lens with
focal length 5.00 cm. A second converging lens with focal length
6.00 cm is located 15 cm to the right of the first lens (a) Find
the distance between the original object and the final image. 1 (b)
If the object height is 0.5 cm, what is the final image height? (c)
Describe the final image in as much detail as possible.

The tube length in a certain compound microscope is 25
cm. The focal length of the objective lens is 2.1 cm. The clearest
image is formed when an object of height 1 mm is placed at a
distance of 2.3 cm from the objective lens. Determine: (i) The
position of the intermediate image, (ii) the focal length of the
eye piece, that will place the final image at the near-point, (iii)
the total magnification of the microscope and the height...
