Question

A plane electromagnetic wave of frequency $$20$$ MHz travels in free space along the $$x-direction$$. At a particular point in a space and time the magnetic field vector is  B→$$=3$$×$$10$$−$$8T$$ k∧. Calculate electric field vector (E$$→$$) at this point

Infinity Learn · Accepted Answer

Step no $$1$$ : Calculate the magnitude of electric fieldWe know, $$E=B$$×c ⇒$$E=3$$×$$10$$−$$8$$×$$3$$×$$108$$ ⇒$$E=9VmStep$$ no :$$2$$ As B¯ is along $$z-$$ direction and wave is travelling along $$x-direction$$ therefore E→ is along $$y-direction$$                 E→$$=9Vmj^$$

A plane electromagnetic wave of frequency 20 MHz travels in free space along the x-direction. At a particular point in a space and time the magnetic field vector is $\vec{B} = 3 \times 10^{- 8} T \overset{\land}{k}$ . Calculate electric field vector $(\vec{E})$ at this point
