optical astronomy

(op -tă-kăl) The study of astronomical objects using radiation with wavelengths from about 300 to 900 nanometers. These wavelengths can pass through the Earth's atmosphere so that observations are possible from the ground. The human eye is sensitive to most of this waveband. See also light; reflecting telescope; refracting telescope.
