Think of it this way though if we cloned ourselves or someone clones us after we die it'll be like we never left. It will bring less heart-ship to people knowing can always have that person. it will also make life more evolved in evolution and theory.
i couldn't think of anything else but her's a start :)
All electromagnetic waves travel at 3*10^8 ms⁻¹ , the equation for wave speed is v=wavelength*frequency. Therefore wavelength=v/f=3*10^8/600000000=0.5m
