Question

If you want your microscope or telescope to project a real image onto a screen, how would you change the placement of the eyepiece relative to the objective?

a. Increase the distance between the eyepiece and the objective.
b. Decrease the distance between the eyepiece and the objective.
c. No change is needed; the default configuration projects real images.
d. Adjust the focus of the eyepiece without changing its distance from the objective.

Answer 1

To project a real image onto a screen using a microscope or telescope, you should increase the distance between the eyepiece and the objective so that the intermediate image lies just beyond the eyepiece's focal length.

Step-by-step explanation:

If you want your microscope or telescope to project a real image onto a screen, you would need to adjust the placement of the eyepiece relative to the objective lens.

Specifically, the eyepiece should be moved slightly farther from the objective so that the image formed by the objective falls just beyond the focal length of the eyepiece.

This setup allows the eyepiece to cast a real image onto a screen, as it is then able to project the image that is located just inside its focal point into real space beyond the lens.
