1.	A double convex lens which has the same radius of curvature for both spherical surfaces is called _________________
Answer» positive or CONVERGING lensExplanation:if both surface have the same RADIUS of curvature,the lens is equiconvex.If the lens is biconvex a collimated beam of light PASSING through the lens converges to a focus behind the lens.In this case the lens is CALLED positive or converging lens.
