Chapter 26: Q15CQ (page 955)

The image produced by the microscope in figure below cannot be projected. Could extra lenses or mirrors project it? Explain.

Short Answer

Expert verified

Yes, the image produced by the microscope in the figure cannot be projected.

Step by step solution

01

Definition of the virtual image.

In optics, an image is defined as the collection of focus points of light rays coming from an object. A real image is the collection of focus points made by converging rays, while a virtual image is the collection of focus points made by extensions of diverging rays.

02

Step 2:

Yes, the image in the microscope is virtual, so it is not possible to project. But the light coming out from a microscope is like the light coming out from some distant object. So the extra lens or mirror can project the image on the screen.

If there is a fixed percent uncertainty in LASIK reshaping of the cornea, why would you expect those people with the greatest correction to have a poorer chance of normal distant vision after the procedure?

The far point of a myopic administrator is 50.0 cm. (a) What is the relaxed power of his eyes? (b) If he has the normal 8.00% ability to accommodate, what is the closest object he can see clearly?

(a) During laser vision correction, a brief burst of 193nm ultraviolet light is projected onto the cornea of the patient. It makes a spot 1.00mm in diameter and deposits 0.500mJ of energy. Calculate the depth of the layer ablated, assuming the corneal tissue has the same properties as water and is initially at 34.00C. The tissue’s temperature is increased to 1000Cand evaporated without further temperature increase. (b) Does your answer imply that the shape of the cornea can be finely controlled?

The contact lens prescription for a mildly farsighted person is 0.750 D, and the person has a near point of 29.0 cm. What is the power of the tear layer between the cornea and the lens if the correction is ideal, taking the tear layer into account?

A microscope with an overall magnification of 800 has an objective that magnifies by 200.

(a) What is the magnification of the eyepiece?

(b) If there are two other objectives that can be used, having magnifications of 100 and 400, what other total magnifications are possible?
