The electric field component of an electromagnetic wave is expressed as E=(3 j+b k) 10⁻³ [10^7(x+2 y+3 z- t) ] in SI units. Taking c=3 10^8 m ~s ⁻¹ as the speed of electromagnetic wave in vacuum, choose the correct option(s)
Options
- AThe value of constant beta is =3 10^8 14
- BThe value of constant b is b =2 .
- CThe average energy density of the em wave is U=6.5 10⁻⁶ ₀ in SI units.
- DThe amplitude of magnetic field is B=1.20 10⁻¹¹ Tesla
Correct answer
