o = 8.85 x 10-12 C2/Nm2
o = 12.56 x 10-7 wb/amp.m

6. .fc 
C = kecepatan cahaya (3 x 108 m/s)
= Panjang Gelombang (m)
1A0 = 10-10Hz
f = Frekuensi (Hz)
1MHz = 106Hz

7. Gelombang elektromagnetik adalah
gelombang yang tidak memerlukan medium
dalam perambatannya.
Radiasi elektromagnetik adalah
kombinasi medan listrik dan medan magnet
yang berosilasi dan merambat lewat ruang dan
membawa energi dari satu tempat ke tempat
yang lain. Cahaya tampak adalah salah satu
bentuk radiasi elektromagnetik.
