Answer
(a) On keeping the lens near a printed page, if letters appear magnified, the lens is convex and if the letters appear diminished, the lens is concave.
(b) Uses of convex lens are:
- Convex lens are used in microscopes and magnifying glasses.
- The objective lens of a telescope, camera, slide projector, etc., is a convex lens which forms the real and inverted image of the object.
