MICROWAVE TELESCOPE, THE PARTS: * A microwave/millimeter-wave telescope can observe space objects in a frequency range between 70 and 300 GHz * some X-ray telescopes use Wolter telescopes composed of ring-shaped 'glancing' mirrors made of heavy metals that are able to reflect the rays just a few degrees.
microwave - a short electromagnetic wave (longer than infrared but shorter than radio waves); used for radar and microwave ovens and for transmitting telephone, facsimile, video and data. radiation - energy that is radiated or transmitted in the form of rays or waves or particles. radio emission, radio radiation, radio wave - an electromagnetic wave with a wavelength between 0.5 cm to 30,000 m.
