42 Fig 4 1 is a ray diagram representing two rays passing through a converging lens A Fig 4 1 a State which of the labelled points is a principal focus of the lens b State which of the distances BX XY YZ or XZ is the focal length of the lens 1 1 c On Fig 4 1 draw another ray from point A to locate the image of point A Label this image I 3 d On the ray diagram in Fig 4 1 the refraction is shown occurring at the centre line of the lens State where the refraction actually occurs
