Question

The wavelength of the oscillatory magnetic field in
a plane electromagnetic wave given by
B = 0.6 x 10-5 sin (4000 tex - 5* 10 ) T is
(where x is meter and t is in second)
(1) 0.4 * 10-3 m
(2) 0.2 x 10-3 m
(3) 0.5 * 10 m
(4) 0.3 * 10-m​

Answer 1

Answer:

Given equation is By=(8×10-6)sin[2×1011t+300πx]T ... (ii)E0=CB 0=3×108×8×10-6=24×102=2400Vm-1
