Description: الموجات الراديوية هي أطول طول موجي وأقل تردد وأقل جزء طاقة فى الطيف الكهرومغناطيسي. وهي تتراوح فيما بين أقصر طول موجي يبلغ حوالي 1 ملليمتر وتردد 300 جيجاهيرتز و عدة كيلومترات في الطول الموجي وميجاهرتز من التردد. غلافنا الجوي شفاف ويسمح لمعظم هذا النطاق الموجي بالمرور خلاله ، مما يمكننا من وضع التلسكوبات الراديوية على الأرض.
