We show that for the asymptotically strong (super-Schwinger) magnetic field B exceeding the critical value B_cr=m²c³/eh=4.4• 10¹³ Gs, the vacuum polarization effects become important not only in the γ-range, but also for softer electromagnetic quanta, including X-rays and optic photons, and for electromagnetic waves of the radio frequencies. This is a consequence of the linearly growing term present in the vacuum polarization in the asymptotically strong magnetic field. The results may be essential in studying reflection, refraction, and splitting of X-rays, light and radio waves by magnetic fields of magnetars, and in considering emission of such waves by charged particles.
