Question

A microscope has an objective lens of focal length+0.50-cm and an eyepiece of focal length+2.6-cm. An object is placed 0.60 cm in front of the objective lens. The final virtual image is100 cm from the eyepiece at the position of minimum eyestrain.

Part A

Determine the separation of the lenses. Assume that the near point distance is 25 cm.

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

Part B

Determine the total angular magnification.

Express your answer using two significant figures.

Explanation / Answer

part a )

1/do + 1/di = 1/fo

1/0.6 + 1/di = 1/0.5

di = 3 cm

L = 3 + 2.6 = 5.6 cm

part b )

-(5.6/0.5) ( 25/2.6)

M = -107.7
