Q1：電波とはどういうものですか？
http://www.goo-buy.com/signal-jammer.html
A1-1：電波法では「電波とは、300万MHz以下の周波数の電磁波をいう。」と規定しています。ここで周波数とは、波が1秒間に振動する回数で単位はHz（ヘルツ）です。
なお、電磁波には電波（300万MHz以下）よりも高い周波数の赤外線や可視光線、紫外線、さらに放射線と呼ばれるX線やγ（ガンマ）線も含まれます。
電波は金属などの導体に電流が流れると磁界と電界が交互に繋がるように発生して空間を伝わることから、送信機や受信機、アンテナを用いて無線通信ができます。
また、電波は宇宙空間のように真空でも伝わりますので、空気の振動で伝わる音波とは違います。
