Radio waves reflect off of the dish and into the tip There are receivers under the tip that intercept the radio waves
We use them to intercept radio waves from space Invented in 1937 by Radio telescopes can measure hydrogen between stars, something that optical these telescopes measure radio waves, enabling them to see into ranges that optical telescopes cants see, Scientists can make false color pictures from these radio waves. telescopes cant do becauseE t astronomer Grote Rever, radio telescopes can search.Contribute in many ways to astronomers zero missionwavelengths of these hydrogen clouds are too long.Objects such as pulsars and quasars are highly energeticand emit radio waves in addition to visible light. Radiotelescopes can read these radio waves and gainadditional information about these objects.
An area with no radio waves from any civilization (eg. TV, computer, radio and GPS) It needs radio waves to function A dish An antenna A stand
