A ray of light passing through principal focus of a convex lens after refraction will emerge
Parallel to the principal axis
A ray of light travelling parallel to the principal axis of the lens, after refraction through the lens, passes through the principal focus (F_2 or F') on the other side of the lens. Therefore, the correct path for a ray of light passing through the principal focus of a convex lens after refraction is that it will emerge parallel to the principal axis .
