In an experimental setup, a spherometer is used to measure the radius of curvature of a spherical surface. The setup includes an equilateral triangle ABC with a distance l between any two legs. Which parameter is used to calculate the radius of curvature R of the spherical surface?
A
Sagitta h
B
Mass of object
C
Plumb line length
D
Beam balance distance
Correct Answer
Option A
Detailed Explanation
The radius of curvature R of the spherical surface is calculated using the sagitta h, which is the distance from the tip of the spherometer to the spherical surface, as described in Chunk 1 of the NCERT context.
