Task id13158
At a distance of 102 cm from a concave mirror, the optical power of which is equal to +2 diopters, there is a point source of light. Between the mirror and the source there is a plane-parallel glass plate whose refractive index is 1.5. At what thickness of the plate will the image coincide with the source? Assume that the size of the mirror is small enough so that the ratio of the tangents of the angles of incidence and refraction of the rays in the plate can be replaced by the ratio of their sines.
