Optics Quiz

The centres of spheres whose parts form surfaces of the lenses are called centres of curvatures of the lenses.

The imaginary line passing through both centres of curvature is called the principal axis of the lens.

The point inside a lens on the principal axis, through which light rays pass without changing their path is called the optical centre of a lens.

<p>They converge to a point on the principal axis, known as the principal focus of the lens.</p> Signup and view all the answers
