Could someone please help me with this?
Use the worked example above to help you solve this problem. A certain microscope has two interchangeable objectives. One has a focal length of 2.1 cm, and the other has a focal length of 0.2 cm. Also available are two eyepieces of focal lengths 2.6 cm and 5.2 cm. If the length of the microscope is 18-cm, compute the magnifications for the following combinations: the 2.1-cm objective and 5.2-cm eyepiece; 2.1-cm objective and 2.6-cm eyepiece; 0.21-cm objective and 5.2-cm eyepiece. 2.1 cm objective and 5.2 cm eyepiece m = 2.1 cm objective and 2.6 cm eyepiece m = 0.21 cm objective and 5.2 cm eyepiece m = Combine the 0.21 cm objective with the 2.6 cm eyepiece and find the magnification. m =Explanation / Answer
magnification M = LD/(fo*fe)
1)
M = (18*25)/(2.1*5.2) = 41.21
2)
M = (18*25)/(2.1*2.6) = 82.42
3)
M = (18*25)/(0.21*2.6) = 824.17
4)
M = (18*25)/(0.21*5.2) = 412.1
