Physics Question on Electromagnetic waves
In E and K represent electric field and propagation vectors of the EM waves in vacuum, then magnetic field vector is given by:(ω− angular frequency):
A
ω1(K×E)
B
ω(E×K)
C
K×E
D
ω(K×E)
Answer
ω1(K×E)
Explanation
Solution
The correct answer is (A) :ω1(K×E)
Magnetic field vector will be in the direction of K^×E^
magnitude of B=CE=ωKE
Or B=ω1(K×E)
