Root Explanation

Spherometer → It is formed from "sphaira" (meaning sphere) and "metron" (meaning measure). A spherometer is an instrument used to measure the curvature of a sphere or a spherical surface.

Memory Tip

Imagine measuring the 'sphere' ('sphaira') with a tool that 'measures' ('metron') its curvature — that's what a spherometer does.
