Question
Please show without the anguar magnification please!
A particular microscope has an objective lens with f = 5 cm and an eyepiece with f = 5 cm. In this configuration, the object (an amoeba that is roughly spherical with a diameter of 0.1 mm) is 10 cm in front of the objective lens, and the eyepiece is 14.5 cm on the other side of the objective. Your eye is 1 cm from the eyepiece (see diagram) a) Determine the location and size of the final image of the amoeba. The solution includes a calculation for something called the "angular magnification" _____ you may ignore this. I won't cover that on your last test b Now you switch objectives. The new objective has f_o = 3 cm. The amoeba and eyepiece stay in the same place, but the new objective is now closer to the amoeba ?(10-40^1/2) cm from the amoeba, and thus (14.5 + 40^1/2) cm from the eyepiece in order to keep the image of the new objective in exactly the same place as the image of the original objective (real microscopes have this feature). Determine the location and size of the final image, and the angular magnification in this case (Is it bigger, smaller, or the same as before?)Explanation / Answer
M= L/Fo (1+ D/Fe).
M= 14.5/5 (1+ 25/5)
= 14.5/5 x 30/5
= 17.5
image will be 17.5 times magnified and formed at infinity.
