To determine the radius of curvature of spherical surface by spherometer readings

Answer 1

Answer:

To find the radius curvature of the spherical surface

Place the spherometer on the concave surface so that its three legs rest on it. Gently turn the screw downwards till the screw tip just touches the concave surface. Note the reading of the circular disc scale which is in line with the vertical (pitch) scale
