Question

give. your. opinion. about. radius. of. curvature. of. a. convex. lens. having. differnt. F1. and. F2. ? What. would. the. lens. called. having. equal. F1. and. F2?​

Answer 1

Answer:

The sides of a lens having different foci look differently curved when seen from a side ; ),while it looks symmetric if it has equal foci. If F1 is greater than f2,the image will be farther away from the optic center than if they were equal,same for the other way round.
