The magnetic field of an E.M. wave is given by $B = (\frac{3}{2} \hat{i} + \frac{1}{2} \hat{j}) 30 sin [ω (t - \frac{z}{c})]$ (S.I. Units).
The corresponding electric field in S.I. units is :

Question

The magnetic field of an E.M. wave is given by B = ( 2 3 ​ ​ i ^ + 2 1 ​ j ^ ​ ) 30 sin [ ω ( t − c z ​ ) ] (S.I. Units). The corresponding electric field in S.I. units is :

TestHub · Accepted Answer

​ B = ( 2 3 ​ ​ i ^ + 2 1 ​ j ^ ​ ) 30 sin [ ω ( t − c z ​ ) ] E = B × c and E = B 0 ​ c ​ Here E ( 2 3 ​ ​ ( − j ^ ​ ) + 2 1 ​ i ^ ) ​ E 0 ​ = 30 c E = ( 2 1 ​ i ^ − 2 3 ​ ​ j ^ ​ ) 30 c sin [ ω ( t − c z ​ ) ] ​
