Abstract

I discuss the question if gravitational lenses have the same effect on static gravitational fields of background objects as they have on light. In this context the behaviour of electrostatic fields, gravitational waves and scalar fields is investigated. In the end I show that weak perturbations of weak gravitational fields can be described similarly to light waves. The answer to the question posed in the title is "No" for static fields and "Yes" for waves of sufficiently small wavelength.
