Considering a telescope with an objective lens with f1=932 mm and an eyepiece with f2=32 mm, at what distance could you resolve a dime (diameter=18.03 mm)? (Use the information from question 3 that the human eye can resolve about 1/60 of a degree, and answer in m.)

This is a two part question. Part 1. To look closely at a small object, such as an insect or a crystal, you bring it close to your eye, making the subtended angle and the retinal image as large as possible. But your eye cannot focus sharply on objects that are closer than the near point, so the angular size of an object is greatest when it is placed at the near point (25 cm away from a “normal” eye)....

9. A simple telescope can be constructed from two convex lenses. Consider a telescope that uses a 500 mm lens (focal length of 500 mm) for the objective lens and a 150 mm lens for the eye piece. 1. How far apart must the lenses be placed to view an object that is 100 m away (from the objective lens) and appears to be 20 cm in front of the eyepiece lens? 2. What magnification does the telescope produce for...

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...

Question 2 (1 point) Saved An object is placed 19.6 cm to the left of a converging lens with a focal length of f=5.3 cm. Where is the image located, and what is its orientation? Odı = 7.26 cm (upright) Odı = 2.66 cm (upright) di = -2.66 cm (inverted) di = 7.26 cm (inverted)

Experiment 22: The Compound Microscope f2 Object 2 1 (Objective Lens)d L, (Eyepiece) d#150mm The Compound Microscope A compound microscope uses two lenses to provide greater magnification of near objects than is possible using a single lens as a magnifier. The setup is shown above. The objective lens, L1, functions as a projector. The object is placed just beyond the focal point of L1 so a real, magnified, inverted image is formed. The eyepiece, L2, functions as a magnifier. It...

Data provided below
The magnitude of the lateral magnification is defined to be imi = Image Height = 4 Object Height h, 3) From geometry this can be shown to be equal to From ur measurements obtained for source-screen distance equal to 85 cm, compare the yo lateral magnification using each of the two relations above. Do this for the first position o the lens (the unprimed measurements) and then for the second position of...
