Question

If at a particular instant and at a certain point in space the electric field is in the x-direction and has a magnitude of 3.80 V/m , what is the magnitude of the magnetic field of the wave at this same point in space and instant in time?

Answer 1

Answer:

The value is  $|\vec B| = 1.267 *0^{-8} \ T$

Explanation:

From the question we are told that  

   The magnitude of the electric fields is  $E = 3.80 V/m$

Generally speed of light is mathematically represented as

        $c = \frac{|\vec E|}{ |\vec B|}$

Here c is the speed of light with value  $c = 3.0*10^{8} \ m/s$

        $|\vec B |$  is the  magnitude of the magnetic field so  

=>         $|\vec B| = \frac{|\vec E|}{c}$

=>         $|\vec B| = \frac{ 3.80 }{3.0*10^{8}}$

=>         $|\vec B| = 1.267 *0^{-8} \ T$
