Question

The amplitudes E0 and B0 of electric and the magnetic component of an electromagnetic wave respectively are related to the velocity c in vacuum as (A) E0 B0 = (1/c) (B) E0 = (c/B0) (C) B0 = cE0 (D) E0 = cB0

As we know, in electromagnetic waves, speed of light, c=(E0/B0) ⇒ E0=C B0

Q. The amplitudes $E_{0}$ and $B_{0}$ of electric and the magnetic component of an electromagnetic wave respectively are related to the velocity $c$ in vacuum as

$E_{0} B_{0} = \frac{1}{c}$

$E_{0} = \frac{c}{B _{0}}$

$B_{0} = c E_{0}$

$E_{0} = c B_{0}$

$E_{0} = c^{3} B_{0}$

As we know, in electromagnetic waves, speed of light,
$c = \frac{E _{0}}{B _{0}} \Rightarrow E_{0} = C B_{0}$

Q. The amplitudes E0​ and B0​ of electric and the magnetic component of an electromagnetic wave respectively are related to the velocity c in vacuum as

E0​B0​=c1​

E0​=B0​c​

B0​=cE0​

E0​=cB0​

E0​=c3B0​

As we know, in electromagnetic waves, speed of light, c=B0​E0​​⇒E0​=CB0​
