Optics and Converging & Diverging Lenses 1. What is the relationship between the curvature of a lens (thick vs thinner converging lenses) and its light-bending power? 2. Focal length: is there a trend in the image distances vis a vis focal lengths as the object distance gets larger? What happens to the thin lens formula when object distance is very large? 3. In the compound lens formula, 1/fcomp = 1/f1 + 1/f2, why does a longer focal lens will not...

When two thin lenses are in contact, the combination may still be considered as a thin lens. The focal distance of the combination, fc, is given by 1 1 1 + eq. (1) fcff2 where fi and f are the focal distances of the two lenses in contact. Assume two converging lenses (10 cm and 20 cm focal distances) are in contact and da = 15 cm. a) Calculate the image distance (d) and magnification (m.) for the combination. (2...

Don't quite get questions 1-6
For lenses in combination, the image for the first lens is the object for the second. The ray tracing diagram below shows how the rays travel through the system from object to first image/second object and then to second image. The first ray trace gives the location and size of the first image. A second ray trace is performed to find where the second object (which is the first image) creates the second image. It...

Which is true of a compound microscope? Question 1 options: Uses two converging lenses The optics are reversed from those of a refracting telescope The object to be viewed to be enlarged is placed just outside the focal point of the lens All of the above An optical surface is converging if . . . Question 2 options: Parallel incident rays are bent so they intersect after interacting with the surface Parallel incident rays are bent so they intersect before...

Two positive thin lenses are separated by a distance of d. The focal lengths of the lenses are f_1 = 10 cm and f_2 = 20 cm. The desired throw of the system, the object to image distance, is T = 80 cm and the desired magnification is M = -1.1. a) Use what you know about the conjugate matrix for a two lens system to solve to the distance between the lenses. Express your answer in cm. b) Where...

Thin lenses. Object O stands on the central
axis of a thin symmetric lens. For this situation, each problem in
the table (below) gives object distance p (centimeters),
the type of lens (C stands for converging and D for diverging), and
then the distance (centimeters, without proper sign) between a
focal point and the lens. Find (a) the image
distance i and (b) the lateral
magnification m of the object, including signs. Also,
determine whether the image is (c) real...
