\n Radio detection and ranging device that emits radio waves and receives them after they bounce on the nearest surface. This creates an image of storms and other nearby objects.\n <\/dd>\n
\n radiation\n <\/dt>\n
\n The movement of energy through empty space between objects by electromagnetic waves.\n <\/dd>\n
\n radiative zone\n <\/dt>\n
\n Layer of the Sun immediately surrounding the core where energy moves atom to atom as electromagnetic waves.\n <\/dd>\n
\n radio telescope\n <\/dt>\n
\n A radio antenna that collects radio waves or microwaves.\n <\/dd>\n
\n radio wave\n <\/dt>\n
\n The longest wavelengths of the electromagnetic spectrum; 1 mm to more than thousands of kilometers.\n <\/dd>\n
\n radioactive isotope\n <\/dt>\n
\n Substance that is unstable and likely to decay into another isotope.\n <\/dd>\n

\n reflecting telescope\n <\/dt>\n
\n Telescopes that use mirrors to collect and focus light.\n <\/dd>\n
