Question

make ray diagram of simple microscope and derive its manifying power in normal adjustment position.​

Answer 1

Answer:

Explanation:

(a) Labelled diagram of compound microscope. The objective lens form image A' B' near the first focal point of eyepiece.

(b) Angular magnification of objective lens m0 = linear magnification h'/h   where L is the distance between second focal point of the objective and first focal point of eyepiece. If the final image A'' B'' is formed at the near point. Angular magnification me = (1+ D/fe) If the final image A'' B'' is formed at infinity, then angular magnification me =D/fe . . .

(2) Thus, total magnification of the compound microscope M = m0 x me

= L/f0 x D/fe

Answer 2

X-ray microscope drawing:

A ray diagram showing the operation of a simple microscope is shown in the image.

The small AB object to be enlarged is placed between the main F ’focus and the C-angle of the convex lens.

Growth capacity in the normal repair area:

The magnitude of the astronomical telescope in normal correction is defined as the ratio of the angle obtained to the eye by the final image to the reduced angle of the eye, by the direct object, where the final image and object both lie at a constant distance. from the eye.

The magnifying power of the astronomical telescope at normal correction is defined as the ratio of the angle lowered to the eye by the last image to the reduced angle of the eye, by the direct object, where the last image and object both lie at a constant distance from. eye.

By reducing the area (width) of the target lens, the amount of sin q decreases, and as a result, the resolution capacity decreases.

In reducing the focus lens of the target lens, the amount of sin q increases, and thus the resolution capacity increases.
