Question

What is a spherical refracting surface?

पर्याय

• A boundary that separates a transparent medium from a vacuum only

• A polished curved surface that reflects light back into the same medium

• A flat boundary separating two transparent media

• A curved boundary separating two transparent media, where one medium has refractive index n₁ and the other has refractive index n₂

Answer 1

A spherical refracting surface is defined as a curved boundary separating two transparent media with refractive indices n₁ and n₂. When light crosses this curved surface, the rays bend due to refraction and an image is formed depending on the curvature and the refractive indices of the two media.
