Question

Write SI unit of radius of curvature of a spherical surface.​

Answer 1

SI UNIT of radius of curvature of spherical mirror is metre (m).

• SI unit means a universal unit which will be followed for a physical quantity anywhere in the world irrespective of the country.

Since radius of curvature of spherical mirror has dimensions of length, the SI unit should be in metres.

Additional info:

• Radius of curvature is defined as the distance between the centre of curvature and the pole of the mirror.

• Centre of curvature is that point through which the light rays pàss and then reflect back to trace back its path.

Answer 2

Answer:

meter

Explanation:

The Spherometer is a device that measures the radius of curvature. A spherometer is a crucial scientific instrument that precisely measures the radius of curvature of any spherical surface. The least count is the smallest value measured by the spherometer. Its S.I unit is meter.

Hence, SI unit of radius of curvature of a spherical surface is meter.
