Question

give your opinion about radius of curvature of a convex lens having different F1 and F2 what would the lens called having equal F1 and F2

Answer 1

Give your opinion about radius of curvature of a convex lens having different F1 and F2 what would the lens called having equal F1 and F2.

Answer:

The sides of the lens which have different focal length, they have different kind of curved sides. They appear to us different when we see it from different side.

If the focal lengths are similar then it will appear as symmetric in nature. If suppose the focal length 1 is greater than focal length 2 then the image that that is present will appear at a distance from the optic centre.  

Answer 2
