Question

When viewing a focused specimen in the microscope, the user sees a speck in the field of view. The speck remains in view when the objective is changed and when the specimen is moved. The speck is most likely located on the:
(A) Condenser
(B) Eyepiece
(C) Objective
(D) Specimen coverslip

• A. Condenser
• B. Eyepiece
• C. Objective
• D. Specimen coverslip

Hint:

To confirm the location of the speck, rotate the eyepiece. If the speck moves with it, it is indeed on the eyepiece.

Answer 1

The Correct Option is B

If the speck remains visible regardless of changes in the objective or specimen movement, it indicates that the speck is located on the eyepiece. This is because the eyepiece remains constant in the optical path and does not change as the objectives or specimen are adjusted.
