A 100mm focal length lens is used to image an object at infinity, If the object has a total angular size of 10mrad, what is the image size?
magnification = v/u = hi/ho
=> h0/u = hi/v
=> Tan(10mrad) = hi/100
=> hi = 64.5 mm

A microscope has an objective lens with a focal length of 10.0 mm . A small object is placed 0.90 mm beyond the focal point of the objective lens. If an eyepiece with a focal length of 2.5 cm is used, with a final image at infinity, what will be the overall angular magnification of the object? Express your answer using two significant figures.
A microscope has an objective lens with a focal length of 15.0 mm . A small object is placed 0.90 mm beyond the focal point of the objective lens. Part A) At what distance from the objective lens does a real image of the object form? My answer: s' = 270 mm Part B) What is the magnification of the real image? My answer: m = -17 Part C) If an eyepiece with a focal length of 2.5 cm is...
Use the thin lens equation to prove that an object at infinity produces an image at the focal length of the lens (i.e. that when p=infinity, q=f) Note that q=12.5 cm
A 50mm focal length thin lens is used to image a 250mm x 250mm object onto a 10mm x 10mm detector. What is the overall object to image distance?
An object is 19.0 cm to the left of a lens with a focal length of +9.5 cm. A second lens of focal length +12.5 cm is 29.5 cm to the right of the lens. Find the location and size of the object of height 1.0 cm. Location with respect to the second lens? What is the height (absolute value) of the image?
A converging lens with a focal length of 40 cm is used to form an image on a screen that is 2.8 m behind the lens. At what distance in front of the lens must the object be placed?
An object is 22.0 cm to the left of a lens that has a focal
length of +8.50 cm. A second lens, which has a focal length of
-29.0 cm, is 5.80 cm to the right of the first lens.
(a) Find the distance between the object and the final image
formed by the second lens.
(b) What is the overall magnification?
Please help with parts A and B. Thanks!
An object is 22.0 cm to the left of a...
A lens of focal length 40 mm is used as a magnifier. The object being viewed is 5.3 mm long, and is positioned at the focal point of the lens. The user of the magnifier has a near point at 25 cm. The angular magnification of the magnifier is closest to 5.
A lens of focal length 10cm is used to produce an image with magnification +3. What must the object distance be?
1 A converging lens with a focal length of 12.2 cm forms a virtual image 7.9mm tall, 11 2emto right of the lens. a. Determine the position of the object. b. Determine the size of the object. Is the image upright or inverted? Are the object and image on the same side or opposite sides of the lens? c. d. 2 You want to use a lens with a focal length of magnitude 36cm with the image twice as long...
