Question

please answer all parts clearly. i am not understanding this problem.

A convex lens with focal length 10 cm is placed 80 cm away from a screen. A candle 5 cm tall is placed in front of the lens in such a location that a magnified image forms on the screen. (a) Calculate the position of the candle. (b) Is the final image upright or inverted? Real or virtual? Explain HOW you determine these. (c) Draw a ray diagram of the set-up containing at least two light rays. Comment on the agreement or lack thereof between your drawing and your calculations.

Answer #1

An object is placed in front of a converging lens (convex lens)
with a radius of curvature of 4.88 cm and focal length of 2.44 cm.
An image is formed the object. (a) Calculate how far is the lens
from the object if the image is real. (b) How far is image from the
lens? (c) is the image upright or inverted, and is the image
magnified or diminished? (d) Draw the ray diagram to confirm your
result prediction.

1) Two convex lenses, both with focal length 1.5 m, are placed
such that the light from a 4 cm tall object passes through each.
The object is placed 4.5 m from the first lens, and the lenses are
3 m apart. Where will the image from the first lens be? Will it be
real or virtual? Will it be upright or inverted? Where will the
final image be (using both lenses)? Will it be real or virtual?
Upright or...

A diverging lens has a focal length of -14.0 cm. Locate the
images for each of the following object distances. For each case,
state whether the image is real or virtual and upright or inverted,
and find the magnification.

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 7·cm tall candle is placed 175·cm from a lens with a focal
length of +35·cm. Note: enter the absolute value of your
answers for all distances and heights ... use the signs to
determine the type and orientation of the images.
(a) How far from the lens will the image
be? cm.
(b) How tall will the image be? cm
Now, imagine that the candle is moved closer, so that it is only
14·cm from the lens.
(d) How far from...

What are the possible situations for convex, concave, and plane
mirrors and lens depending on the image location from the focal
point? For example when an object is placed farther from a convex
mirror than the focal length, the image would small or enlarged and
virtual or real and upright or inverted?

A 6-cm-high candle is placed in front of a converging lens with
a focal length of magnitude 30 cm. If the image distance is +50 cm,
then
find the image height of the candle and whether it is upright or
inverted.
answer: 4cm, inverted
i need help understnading which eqution to use to complete this
problem. Also could you explain how ot determine if an image is
real, inverted, or upright? thank you will rate asap

An object 13 cm tall is located 37cm from a converging lens with
a focal length of 45cm. Find the location and height of the image,
and whether the image is upright or inverted, and whether it’s real
or virtual.
