Answer:

bi convex lens is made from two spheres of different radii focus is marked from both spherical surfaces and focal length is measured on both sides will focal length be equal on both sides imagine and

Answer 2

No, the focal length will not be equal on both sides.

• The focal length of a convex lens depends on two parameters: the radius of curvature of the lens and the refractive index of the lens.
• If the two spheres have different radius then they would have different radius of curvature therefore the focal lengths the biconvex lens on both the sides will be different.
• Focal length is directly proportional to the radius of curvature and the refractive index.
