Question

In an electromagnetic wave electric field and magnetic field is given by
E = E0 sin (kx – ωt + ϕ)
B = B0 sin (kx – ωt + ϕ)
Find correct relation.

• A. $\frac{ω}{k}$ = $\frac{E_0}{B_0}$
• B. $\frac{E_0}{B_0}$ = $\frac{ω}{k}$
• C. $\frac{ω}{k}$ = B0
• D. $\frac{ω}{k}$ = E0B0

Answer 1

Answer: (A)

$\frac{ω}{k}$ = $\frac{E_0}{B_0}$

Answer 2

E0 = B0C
Speed of light C = $\frac{ω}{k}$
$\frac{E_0}{B_0}$ = $\frac{ω}{k}$
So, the correct option is (A) :$\frac{ω}{k}$ = $\frac{E_0}{B_0}$
