[ noun ] (physics) device that reflects radiation
Used in print(Cornell H. Mayer, "Radio Emission of the Moon...)
This is much smaller than the highest resolution of even the very large reflectors now under construction , and consequently the radio_emission of different regions of the disk cannot be resolved .
It should be possible , however , to put useful limits on the diameters of the radio_sources by observing with large reflectors or with interferometers .
The measurements made with the NRL 50 - foot reflector , which is altitude azimuth mounted , would have shown a systematic change with local hour_angle in the measured intensities of Venus and Jupiter if a substantial part of the radiation had been linearly polarized .
Very recently , observations have been made at 8 - mm wave_length with a reflector 22 meters in diameter with a resultant beam width of only about 2 ' ( Amenitskii , Noskova , and Salomonovich , 1960 ) .
Measurements at 3.15 cm were obtained on 11 days spread over the interval May 3 to June 19 , 1956 , using the 50 - foot reflector at the U.S._Naval_Research_Laboratory in Washington .
[ noun ] (astronomy,optics) optical telescope consisting of a large concave mirror that produces an image that is magnified by the eyepiece
