Reflection of waves from a ridged surface is interpreted as the spatial Zeno effect. This interpretation leads to a simple estimate for the coefficient of reflection. This estimate shows good agreement with experimental data of scattering of cold atoms from ridged surfaces.

Key words: Zeno effect, quantum reflection, specular reflection, cold atoms, atomic mirror, atom optics, screen problem
