In the same way, an image of will be formed at A; and images of each point in HO, at corresponding points of AB. 89 If AB is an object placed beyond C, the centre of cur- vature, an inverted and diminished image HO, will be formed between C and the principal focus. Because, if the luminous point is in either conjugate focus, the rays emanating from it will [75] converge to the other. 90 The relative positions of the image and object may be determined from what has been already said [73]. Their relative sizes will be as the squares [41] of their distances from the centre of the mirror. prev next |
