6(a)(i)[4]
two correct rays from:
ray from X through centre of lensray from X to lens, parallel to principal axis, refracted through RH focus Fray from X (that would pass through LH focus) refracted parallel to principal axis.two rays correctly extended back, intersecting to left of object and image labelled
IY drawn AND 36 mm ≤ distance ≤ 44 mm
6(a)(ii)[2]
any two from:
object closer to lens than (one) focal length(actual) rays do not meet (at image)image cannot be formed on a screen OR image only visible through lensobject and image on same side (of lens) OR image on LHS of lens/object.6(b)[3]
blue ray refracted closer to the normal than the green ray as it enters the prism
C1 blue ray refracted away from the normal as it leaves the prism
