Sample questions
-
1.In the ray diagram shown below, a convex lens forms an image of a candle flame on a screen. Classify the image labelled 'I' as real or virtual.
- A.Real, because the rays converge on the other side of the lens
- B.Virtual, because the image can be seen without a screen
- C.Virtual, because the rays appear to diverge from the image
- D.Real, because the image is upright and magnified
-
