The statement 'The eyepiece of the phase contrast microscope is called the objective' is true.

• A. True
• B. False (ocular)
• C. False (eyepiece)
• D. False (condenser)

Answer: (B)

The main idea here is distinguishing microscope parts by their proper names. In a phase-contrast microscope, as in other light microscopes, the lens closest to the specimen is the objective, which creates a magnified image of the sample. The lens you look through at the top is the eyepiece, also called the ocular, which further magnifies that image for viewing.

The statement is false because the eyepiece is not called the objective; the eyepiece is the ocular. The term objective refers to the lens system near the slide, while the eyepiece (ocular) is the lens you observe through. So the correct way to describe the part you look through is that it’s the ocular, not the objective.
