What is the electric field amplitude of an electromagnetic wave whose magnetic field amplitude is 2.0mT ?

Short Answer

Expert verified

The electric field amplitude of an electromagnetic wave is6脳105V/m.

Step by step solution

01

Formula for electric field amplitude

As it stands,

B=2.0mT

c=3脳108m/s

Electric field amplitude is,

E=B路c

Bis magnetic field amplitude.

localid="1648800544485" cis in a vacuum, the speed of light .

02

Calculation for Electric field amplitude

Electric field amplitude,

E=B路c

Substitute all values,

E=2.0脳10-3T脳3脳108m/s

E=6脳105V/m
