Raydiagrams of convexlensClass 10

a. Use ray tracing to find the position and height of the image. Do this accurately using a ruler or paper with a grid, then make measurements on your diagram.

A standardized biological microscope has an 8.0mmfocal length objective. what focal-length eyepiece should be used to achieve a total magnification of100x?

Raydiagram examples

The objective lens of a telescope is a symmetric glass lens with 100cmradii of curvature. The eyepiece lens is also a symmetric glass lens. What are the radii of curvature of the eyepiece lens if the telescope’s magnification is 20×?

A converging lens with a focal length of 40cmand a diverging lens with a focal length of -40cmare 160cmapart. A 2cmtall object is 60cmin front of the converging lens.

(b). Building a telescope of the necessary size does not appear to be a major problem. What practical difficulties might prevent professor Dhg's experiment from succeeding?

High-power lasers are used to cut and weld materials by focusing the laser beam to a very small spot. This is like using a magnifying lens to focus the sun’s light to a small spot that can burn things. As an engineer, you have designed a laser cutting device in which the material to be cut is placed 5.0 cm behind the lens. You have selected a high-power laser with a wavelength of 1.06 mm. Your calculations indicate that the laser must be focused to a 5.0@mm@diameter spot in order to have sufficient power to make the cut. What is the minimum diameter of the lens you must install?

Alpha Centauri, the nearest star to our solar system is 4.3light years away. assume that alpha centauri has a planet with an advanced civilization. professor Dhg, at the planet's Astronomical Institute, wants to build a telescope with which he can find out whether any planets are orbiting our sun.

The rays leaving the two-component optical system of FIGUREP35.27produce two distinct images of the1.0cm-tall object. what are the position (relative to the lens), orientation, and height of each image?

(a). What is the minimum diameter for an objectives lens that will just barely resolve Jupiter and the sun? The radius of Jupiter's orbit is 780millionkm.Assume λ=600nm.
