The diffraction-limited resolution of a 10-meter telescope is about 0.01 arcsecond for visible light. Would you expect the angular resolution of a 10-meter radio telescope to be better than, equal to, or worse than 0.01 arcsecond? Explain.

It would be worse than 0.01 arcsecond because radio waves have much longer wavelength than visible light, and hence poorer angular resolution for the same size telescope.
