JEE Main 2024 — 27 January, Shift 1 — Question 35
Identify the physical quantity that cannot be measured using spherometer :
- Option A:
Radius of curvature of concave surface
- Option B:Correct
Specific rotation of liquids
- Option C:
Thickness of thin plates
- Option D:
Radius of curvature of convex surface
Answer: B
Step-by-step solution
A spherometer is used to measure the radius of curvature of spherical surfaces and the thickness of thin plates. It cannot measure the specific rotation of liquids, which is an optical property measured using a polarimeter.
