4.

A microscope has a 12.0 ×× eyepiece and a 63.0 ×× objective lens 18.0 cmcm apart. Assume a normal eye and that the final image is at infinity.

Part B

Calculate the focal length of the eyepiece lens.

Express your answer to two significant figures and include the appropriate units.

Part C

Calculate the focal length of the objective lens.

Express your answer to three significant figures and include the appropriate units.

Part D

Where the object must be for a normal relaxed eye to see it in focus?

Express your answer to three significant figures and include the appropriate units.

Solutions

Expert Solution

The concept used in this question is of lens formula , magnification of lens under normal adjustment  , i just use the magnification value given in the problem and then use this value in my equation and finally deduced the value asked in the different parts.

Note :- As the final image is formed at infinity which mean object is placed at the focal length of the eye piece .
