Question

An electromagnetic wave has frequency \(50\,MHz\) and electric field amplitude \(5.6\,V\,m^{-1}\). Find the magnetic field amplitude.

• A. \(1.9\times10^{-8}\,T\)
• B. \(1.8\times10^{-8}\,T\)
• C. \(2.0\times10^{-8}\,T\)
• D. \(5.6\times10^{-8}\,T\)

Hint:

For electromagnetic waves, \[ E_0=cB_0. \] The electric and magnetic fields are always perpendicular to each other and to the direction of propagation.

Answer 1

The Correct Option is A
