The amplitude of the magnetic field part of an electromagnetic wave in vacuum is Bm = 510 nT. Then the amplitude of … 102 V/m (D)…
Answers:
The correct option is (C) 1.53 × 102 V/m
Explanation:
Bm = 510 nT = 510 × 10–9T
Amplitude of electric part is Em
& (Em / Bm) = C
Hence Em = C × Bm
= 3 × 108 × 510 × 10–9
= 153 V/m
= 1.53 × 102 V/m
