Can u please write two pages on lens history and what
are lenses.... Applications in today's life... Please don't copy
from online sources... If its ur own work one page is also
good
blue light lenses
You can write about a blue light lens
The only criteria is that the write up must touch on 3
areas:
What is the problem this product (or technique) can solve
What are its limitations
What are its competing products
This is basically an essay about an optical product that you
either are familiar with, or research. No calculations, no maths,
and no more than 2 pages.
A simple camera telephoto lens consists of two lenses. The
objective lens has a focal length f1 = 38.7 cm . Precisely 36.3 cm
behind this lens is a concave lens with a focal length f2 = -10.0
cm . The object to be photographed is 3.97 m in front of the
objective lens How far behind the concave lens should the film be
placed? What is the linear magnification of this lens
combination?
A lens system consists of two lenses 14.0 cm
apart. The first lens is convex (converging) and has a focal length
of 6.72 cm. An object is placed 3.29 cm in front
of the first lens and produces an image 7.00 cm behind the
second lens.
Q1:What is the focal length of the second
lens?
A:5.215 cm
Q2:What is the magnification of the final
image?
A2:
Please provide A2 and show all work, I already
have the correct answer to...
Imagine you have two converging lenses. Lens A has a focal
length of 12.5 cm. Lens B has a focal length of 50.0 cm. The
diameter of each lens is 6.50 cm. Assume a near point of 25.0
cm.
a) How could you make a microscope with
4x magnification using these lenses?
b) How could you make a telescope with
4x magnification using these lenses?
c) Which of these is more practical?
Why?
A two lens magnifying system uses lenses of focal lengths 2.5
and 9.5 cm for the objective and eyepiece, respectively. The two
lenses are positioned 23 cm apart. An object for study is placed
3.0 cm in front of the objective lens. Find the magnification of
the final image.
Two lenses are separated by L = 50.0 cm. The first lens (light
coming from the left.) has a focal length f1 = 24.0 cm and the
second lens has a focal length f2 = 18.0 cm. An object is located
40.0 cm (s1) to the left of the first lens. Calculate the position
of the two images formed by the lens system. State whether each
image is real or virtual. Repeat this problem with L = 10.0 cm.
Two identical diverging lenses are separated by 17 cm. The focal
length of each lens is -8.0 cm. An object is located 4.0 cm to the
left of the lens that is on the left. Determine the final image
distance relative to the lens on the right.
Two converging lenses are separated by 29.00 cm. The focal
length of each lens is 17.00 cm. An object is placed 32.00 cm to
the left of the lens that is on the left. Determine the final image
distance relative to the lens on the right.
