C
Correct answer
Explanation
(I) Statement (1) is wrong. A camera works on the refraction of light through a convex lens.
(II) Statement (2) is wrong. The process in which an eye can adapt itself to see objects at different distances is called accommodation.
(III) There are three types of optical telescopes:
- Refracting telescope - Uses lens to form an image
- Reflecting telescope - Uses an arrangement of mirrors to form an image
- Catadiopteric telescope - Uses mirrors combined with lenses to form an image
