Which statement about a diverging lens is not correct?
A ray of light parallel to the principal axis is refracted so that it appears to diverge from the principal focus.
The principal focus of a diverging lens is a real point where refracted light rays actually meet.
The distance between the centre of the lens and the principal focus is the focal length.
A ray of light passing through the centre of the lens passes straight through without deviation.
