Answer 2

$\mathcal{\huge{\underline{\underline{\orange{Convex\:Lens}}}}}$

• The convex lens is a converging lens as it collects the refracted rays , The point of collection of the parallel rays produced from the sun or any distant object after being refracted from the convex lens is called the focus of the lens ( F ) .

• The distance between the focus of the lens and its optical center is called the focal length of the lens f The focal length ( f ) = ½ × radius of curvature ( r) .

• The piece of paper can be burned by a convex lens because the convex lens can converge and direct the sunlight in a point focus which is burned .

• If we have thin lens and thick lens.

• The thin lens has greater focal length than the thick one because the radius of the thin lens is bigger than that of the thick lens .
