An electromagnetic wave from a wire antenna travels (from the
reader) toward the plane of the paper. At time t = 0.0 s it strikes
the paper at normal incidence. At point O and t = 0.0 s, the
magnetic field vector has its maximum value,
4.00×10-8 T, pointing in the negative y-direction.
The frequency of this wave is 2.57×106 Hz.
What is the x-component of the associated electric
field E at time t = 0.0 s? (Use the
right-hand rule to determine the direction
of E, and hence the sign of the
x-component.)
1.20×101 V/m
What is the magnitude of the Poynting vector of the wave at time
t = 0.0 s?
What is the y component of the magnetic field at point O at time
1.95×10-7 s?
4.00×10-8 T
I need the process of each question and also the response for
the second one!
