A biconvex lens, also known as a double convex lens, is a type of lens with two outward-curving surfacses that are both convex in shape. the term biconvex indicates that both sides of the lens have a convex curvature. these lenses are thickner at the centre and thinner at the edges.
Different between plano convex lens and biconvex lens
Convex and biconvex are both types of lenses with outwardly curved surfaces, but they have distinct differences, there covered in the table as below
Propterties
Plano convex lens
biconvex lens
Shape
A convex lens is thicker at the center and thinner at the edges
A biconvex lens is convex on both sides that is outwardly on both surfaces
Properties
A convex lens converges light rays passing throughit ,it brings parallel rays of light to a focus a point called the focal point, forming a real image if the object is beyong the focal point and a virtual image if the object is closer than the focal point
A biconvex lens also converges light rays, it…
