Question

You have a 35X objective lens in place, and the numerical aperture of the objective lens is 0.75. The numerical aperture of the condenser lens is 1.25. What is the total magnification if the ocular lens is 10X, with the eyepieces spaced 3 cm apart?

Answer 1

350x

Step-by-step explanation:

In a microscope the objective has higher magnification than the eyepiece so, this is a microscope

The magnification of a microscope is given by the product of the magnifications of the eyepiece and and the objective.

Objective lens magnification = 35x =
`m_o`

Eyepiece magnification = 10x =
`m_e`

Total magnification

`M=m_o* m_e\\\Rightarrow M=35* 10\\\Rightarrow M=350`

Total magnification is 350x
