Question

Match List - I with List - II. List - I List - II
A. Compound microscope I. Has a polarizer and an analyzer
B. Stereo microscope II. Permits viewing of two objects at once
C. Comparison microscope III. Long working distance, three-dimensional
D. Polarizing microscope IV. Basic two convex lens microscope
Choose the correct answer from the options given below :

• A. A-IV, B-II, C-III, D-I
• B. A-II, B-IV, C-I, D-III
• C. A-I, B-II, C-III, D-IV
• D. A-I, B-IV, C-II, D-III

Hint:

Polarizing → polarizer + analyzer; Compound → two lenses; Stereo → 3D view.

Answer 1

The Correct Option is A

Concept: Different microscopes are designed with specific optical arrangements to serve distinct purposes in scientific and forensic investigations.

Step 1: Compound Microscope (A).
A compound microscope uses two convex lenses (objective and eyepiece) to magnify objects.
Thus, A $\rightarrow$ IV.

Step 2: Stereo Microscope (B).
A stereomicroscope allows viewing of objects in three dimensions and can observe multiple features simultaneously.
Thus, B $\rightarrow$ II.

Step 3: Comparison Microscope (C).
A comparison microscope enables side-by-side viewing of two specimens (e.g., bullets), effectively comparing them. It also maintains sufficient working distance.
Thus, C $\rightarrow$ III.

Step 4: Polarizing Microscope (D).
This microscope contains a polarizer and analyzer to study birefringent materials.
Thus, D $\rightarrow$ I.

Step 5: Final matching.
\[ A-IV,\quad B-II,\quad C-III,\quad D-I \] Final Conclusion:
Hence, the correct answer is option (1).
