Question

general property of refraction of light through spherical lens​

Answer 1

IN CASE OF CONVEX LENS

•when light travel through convex lens , the rays parallel to the principal axis, after refraction converged to a point called focus.

IN CASE OF CONCAVE LENS

•when light travel through a concave lens, the ray parallel to the principal axis appears to diverge from a point called focus.

Answer 2

If going through focus then goes parallel to principle axis
