Show the answer and mark scheme
4(a)(i)[2]
(point on principal axis) where rays of light parallel (to the principal axis, incident on converging lens)
(rays) meet / converge after passing through lens / refraction
4(a)(ii)[1]
X marked between one of the focal points and the lens AND E marked on other side of lens
4(a)(iii)[1]
virtual AND upright
4(b)(i)[2]
2.0 × 108 m / s
n = c / vg OR (vg =) c / n OR (vg =) 3(.0) × 108 / 1.5
4(b)(ii)[1]
(wavelength) decreases
4(c)[3]
long-sightedness
it moves the image towards the lens / back of the eye / retina OR reduces / shortens focal length of (combined lens) (converging lens) focuses image on back of eye / retina
