Concept explainers
(a)
Where the image is formed by the objective.
(a)
Answer to Problem 29E
The image formed by the objective is
Explanation of Solution
The image formed by the objective is real and inside the focal length of the ocular.
Write the thin lens formula
Here,
To find the image distance from ocular lens,
Substitute
Solving further,
From Figure 24.19, the distance between the lenses,
Here,
Substitute
Conclusion:
The image formed by the objective is
(b)
The distance between the specimen and the objective lens.
(b)
Answer to Problem 29E
The distance between the specimen and the objective lens is
Explanation of Solution
To solve for
Substitute
Solving further,
Conclusion:
Thus, the distance between the specimen and the objective lens is
(c)
The magnification of the microscope.
(c)
Answer to Problem 29E
The magnification of the microscope is
Explanation of Solution
Write the expression to find the magnification of the microscope
Here,
Substitute
The negative sign indicates the image is inverted.
Conclusion:
Thus, the magnification of the microscope is

- Two stars that are 109km apart are viewed by a telescope and found to be separated by an angle of 105 radians. If the eyepiece of the telescope has a focal length of 1.5 cm and the objective has a focal length of 3 meters, how far away are the stars from the observer?arrow_forwardA lamp of height S cm is placed 40 cm in front of a converging lens of focal length 20 cm. There is a plane mirror 15 cm behind the lens. Where would you find the image when you look in the mirror?arrow_forwardTwo thin lenses of focal lengths f1 = 15.0 and f2 = 10.0 cm, respectively, are separated by 35.0 cm along a common axis. The f1 lens is located to the left of the f2 lens. An object is now placed 50.0 cm to the left of the f1 lens, and a final image due to light passing though both lenses forms. By what factor is the final image different in size from the object? (a) 0.600 (b) 1.20 (c) 2.40 (d) 3.60 (e) none of those answersarrow_forward
- You view an object by holding a 2.5 cm-focal length magnifying glass 10 cm away from it. How far from your eye should you hold the magnifying glass to obtain a magnification of 10 ?arrow_forwardHow far should you hold a 2.1 cm-focal length magnifying glass from an object to obtain a magnification of 10 x ? Assume you place your eye 5.0 cm from the magnifying glass.arrow_forwardWhat is the magnification of a magnifying lens with a focal length of 10 cm if it is held 3.0 cm from the eye and the object is 12 cm from the eye?arrow_forward
- Au object of height 3.0 cm is placed at 25 cm in front of a diverging lens of focal length 20 cm. Behind the diverging lens, there is a converging lens of focal length 20 cm. The distance between the lenses is 5.0 cm. Fluid the location and size of the final image.arrow_forwardIn Figures CQ36.11a and CQ36.11b, which glasses correct nearsightedness and which correct farsightedness?arrow_forwardFor a normal, relaxed eye, a magnifying glass produces an angular magnification of 4.0. What is the largest magnification possible with this magnifying glass?arrow_forward
- A converging lens has a focal length of 10.0 cm. Locate the object if a real image is located at a distance from the lens of (a) 20.0 cm and (b) 50.0 cm. What If? Redo the calculations if the images are virtual and located at a distance from the lens of (c) 20.0 cm and (d) 50.0 cm.arrow_forwardA nearsighted man cannot see objects clearly beyond 20 cm from his eyes. How close must he stand to a mirror in order to see what he is doing when he shaves?arrow_forwardWhere does an object need to be placed relative to a microscope for its 0.50 cm-focal length objective to produce a magnification of —400?arrow_forward
