What will happen to the focal length of a concave mirror, convex mirror, concave lens and convex lens when immersed in water? will it change ? if yes explain . View Solution Q2 Why focal length of convex mirror and convex lens is positive while concave mirror and concave len...
These lenses have a positive focal length and near-best-form shape for infinite and finite conjugate applications.Plano-convex lenses can focus a collimated beam or collimate light from a point source. To minimize the introduction of spherical aberration, a collimated light source should be incident...
These dual lenses have a positive focal length and are optimized for infinite conjugation ratios. Double lens pair Achromatic dual lens pairs have the advantages of achromatic lenses and are optimized for finite conjugation. These lens pair...
Abiconvexlens has a convex surface and a double surface, and has a positive focal length. It is usually used for related applications such as beam reduction, focal length reduction, or image enlargement. In order to reduce spherical aberration, the biconvex lens is used to collimate the beam...
A plano-convex lens is compose of a plane and convex surfaces, has a positive focal length.It is used for the changing between point light source and parallel beam.It is mean when the light through the convex surface and out from plano surface,the lens will collect t...
