How to draw the first and second principal planes for ball lens?
The thick lens shown at right is made from glass with index of refraction 1.50. The thick lens has thickness of 6.0 cm and radii of curvature of 8.00 cm and 10.00 cm. (a) Find the focal length of this thick lens in air and the position of its focal points (F and F) and its principal points (H, and H,) with respect to the front and back of the lens respectively. (b) Draw a sketch showing the locations of...
Cv A thin convex lens perpendicular to the rays. The imaginary line perpendicular to the lens and running exactly through the center is referred to as the optical axis or principal axis. Note that it is necessary to place the lens on the front half of the table to observe the intended phenomenon. Dim the class lights and observe the refracted rays 21 What is the focal length of the lens? Answer: 13 cm Use a thick block half lens....
When a converging lens is used in a camera (as in the first drawing), the film must be placed at a distance of 0.160 m from the lens to record an image of an object that is 4.00 m from the lens. The same lens is then used in a projector (as in the second drawing), with the screen 0.530 m from the lens. How far from the projector lens should the film be placed? Film Real mage inverted) Object...
Two converging lenses are separated by a distance of 20 cm. The first lens has a focal length of 5 cm and the second lens has an unknown focal length that you need to calculate. When an object is placed 8 cm in front of the first lens you measure a total magnification of M=-1.8 (That is, the magnification caused by the two lenses). Answer the following questions: 1. location of the image found by the first lens 2. magnification...
16. A lens of focal length 20cm is followed by a second to its right with a focal length -100cm and separated from it by 15 cm. An object is placed 1 meter from the first lens. The resulting mage of the lens combination will be: a. Real, 11cm to the right of the second lens, inverted, and 0.28 times the height of the object. b. Virtual, 20cm to the left of the second lens, inverted and 0.20 times the...
Two thin lenses with focal lengths of magnitude 18.0 cm, the first diverging and the second converging, are placed 11.00 cm apart. An object 3.70 mm tall is placed 4.75 cm to the left of the first (diverging) lens. (a) Where is the image formed by the first lens located? (b) How far from the object is the final image formed? (c) Is the final image real or virtual? (d) What is the height of the final image? (e) Draw...
(optical engr) An optical imaging system includes two thin lenses. The first lens has focal lengths f1 = 5 cm and f2 = 10 cm. The distance between the 2 lenses is 5 cm. An object with height h = 2.5 cm is placed 15 cm before (to the left of) the first lens. A. Use the lens equations to compute final image location and image size of the object in this two lens optical imaging system B. Plot an...

1. What does the beam
look like when it emerges from the second lens?
2. Briefly explain
your reasoning.
A parallel laser beam of width w1 is incident on a two lens system as shown below. Each lens is converging. The second lens has a larger focal length than the first (fz f) 1) What does the beam look like when it emerges from the second lens? O The beam is converging ○The beam is diverging O The beam is...
