An electromagnetic wave in vacuum has an electric field amplitude of 470 v/m. calculate the amplitude of the corresponding magnetic field.

Magnetic field, B =

Explanation:

It is given that,

The amplitude of an electromagnetic wave, E = 470 V/m

We need to find the amplitude of the corresponding magnetic field. The relation between electric and magnetic field is :

Where

c is the speed of light

B = 0.00000156

So, the amplitude of the corresponding magnetic field is . Hence, this is the required solution.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
