Задача 40465.

A converging lens produces an image of an object on a screen. A glass plane-parallel plate with a thickness of d=4 cm and a refractive index of 1.4 is installed between the lens and the screen parallel to the plane of the lens. How should the screen be shifted to again obtain a clear image of the object? Consider the angles of incidence to be small.
