A microscope is focused on an amoeba. When a 0.15-mmthick cover glass (n = 1.50) is placed over the amoeba, by how far must the microscope objective be moved to bring the organism back into focus? Must it be raised or lowered?
Two lenses are placed along the x axis, with a diverging lens of focal length -7.60 cm on the left and a converging lens of focal
length 15.0 cm on the right. When an object is placed 12.0 cm to the left of the diverging lens, what should the separations of the
two lenses be if the final image is to be focused at x = ∞o?
cm
The distance between the eyepiece and the objective lens in a certain compound microscope is 23.0 cm. The focal length of the eyepiece is 1.50 cm, and that of the objective is 0.50 cm. What is the overall magnification of the microscope? (b) The desired overall magnification of a compound microscope is 200. The objective alone produces a lateral magnification of 15.0. Determine the required focal length of the eyepiece.

- For 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_forwardWhy is the following situation impossible? Consider the lensmirror combination shown in Figure P35.55. The lens has a focal length of fL = 0.200 m, and the mirror has a focal length of fM = 0.500 m. The lens and mirror are placed a distance d = 1.30 m apart, and an object is placed at p = 0.300 m from the lens. By moving a screen to various positions to the left of the lens, a student finds two different positions of the screen that produce a sharp image of the object. One of these positions corresponds to light leaving the object and traveling to the left through the lens. The other position corresponds to light traveling to the right from the object, reflecting from the mirror and then passing through the lens.
