Using the black box model of lens, calculate the image coordinates of object points shown in the figure. The focal length f of the lens is 10. The coordinate is defined as (s-value, height)
Homework Answers
The mirror equation expresses the quantitative relationship between the object distance (do), the image distance (di), and the focal length (f). The equation is stated as follows:
The magnification equation relates the ratio of the image distance and object distance to the ratio of the image height (hi) and object height (ho). The magnification equation is stated as follows:

An object is located 26.0 cm from a certain lens. The lens forms a real image that is twice as high as the object. What is the focal length of this lens? Now replace the lens used in Part A with another lens. The new lens is a diverging lens whose focal points are at the same distance from the lens as the focal points of the first lens. If the object is 5.00 cm high, what is the height...

A Lens and a Mirror
In the figure below a converging lens is located at 0
cm. It has a focal length of f1 = 20.2
cm. An object is placed at a = 25.2 cm to the
left from the converging lens. In addition a concave mirror with
focal length of f2 = 10.4 cm is located L = 117.21
cm to the right of the lens.

Consider an object, an image and a lens. Think about how to place the object, image and lens such that the magnification is M = +1.5 and that the image is located 30 cm from the lens. What is the focal length of the lens that you must use? (Hint: First draw out possible scenarios before to decide on the best relative placements before attempting to find f.)

Part A: Investigation of lens behaviors using a distant object Go to a room that has an outside window. With only the windows cracked open and all other lights off, use the reading glasses (or, more easily, the magnifying glass) and see if you can capture the light of something outside the window (perhaps a tree, or a light post or anything you can see outside the window) and “project” the captured light on to a screen (this screen can...
