Question

what is lens simulator in physics?

Answer 1

Lens simulator is just a software that allows simulations of different kinds of refraction happening with convex and concave lenses. For instance, you can choose a type of lens, size of the object, the distance between the object and the lens, adjust the refractive index and focal length, and see how the image is formed under these various conditions. There are many online and offline lens simulators.
