Question

what is sagita of a spherometer​

Answer 1

Explanation:

Most spherometers were small devices, usually ranging from four or five centimeters to less than twenty centimeters across and were predominantly used by lens makers to precisely measure the curvature of a lens.

Answer 2

here is your answer!!!!!☺

spherometer basically is a precision instrument to measure very small lengths. Its name reflects the way it is used to measure the radii of curvature of spherical surfaces.a spherometer can measure both a positively or negatively curved surface to high accuracy. ... The micrometer measures the distance above or below the plane of the three legs. In optics, the distance h is called the sagitta, referred to using the letter h or s, for the depth of glass removed from a lens.as the given information the sagita of spherometer measures a micro distance.
