When a ray of light hits the boundary between the air and the front side of the converging lens, the inward refraction (towards kâ) occurs because of the air - glass interface.
On the other side of the lens the refracton is in ouward direction (away from kâ), because of the opposite interface of the glass â air.
Because the refraction is determined by the angle of refraction, which is related to perpendicular axis of impact, the rays refract on the converging lens towards the optical axis.
