Question

How does the curvature of the lens affects the focal length? Do you think this relationship also is true for mirrors?

Answer #1

What is the relationship between the curvature of the lens and
the focal length?

5.26* Determine the focal length in air of a thin biconcave lens
having
equal radii of curvature of 12.5 cm and an index of 1.5. What
will
happen to the focal length of this lens we submerge it in carbon
disulfide
(n = 1.628)?

A converging lens is made using glass with index 1.5. The
desired focal length is 60 cm. If one side of the lens is convex
with radius of curvature 20 cm, how should the other side be
made?

An object is 17.4 cm to the left of a lens with a focal
length of 12.4 cm. A second lens of focal length 14.7
cm is 54.91 cm to the right of the first lens.
The height of the object of is 3.6 cm.
What is the location of the final image with respect to the
second lens?
What is the height of the image?
Also determine is the image real or virtual and, with
respect to the original...

Imagine you have two lenses at your disposal, lens A of focal
length 18 cm and lens B of focal length -14 cm.
a)An object is placed 33 cm to the left of lens A. Where is the
image located?
b)Now, lens B is also placed 12 cm to the right of lens A. Where
is the final image of the lens combination located?
c) What is the total magnification?
Please be detailed with part B please! (u dont need...

What kind of lens (type and focal length) would you need to place
next to a converging lens of focal length 25cm to create a
converging lens with a focal length of 40cm?

Why does a large radius of curvature give a large focal point
and why does a small radius give a small focal? Using Snell's law
to explain.
Why do light rays that strike the edge of the lens bend more
than light rays that strike the center? Using Snell's Law and the
behavior of Principal Rays to explain.

#8.) Describe in brief two methods to measure
(a) focal length of a lens and
(b) radius of curvature of a spherical surface. Indicate
accuracies achievable in each case.

You are examining a flea with a converging lens that has a focal
length of 3.90 cm .If the image of the flea is 7.00 times the size
of the flea, how far is the flea from the lens? Where, relative to
the lens, is the image?

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...
