An electromagnetic wave propagates in
the + z direction and travels away from the
source over time. Consider wave function \psi
as sine wave and \psi describe an electric
field.
a) In z = 0 and t = 0 the value of the
function \psi is equal to -A where A is the
amplitude of wave, in z = \frac{\lambda}{2} and t = 0 the
value of the \psi is +10. Calculate the
unknown parameters of the wave and
rewrite the wave function
b) Obtain the magnetic field vector
(changes in the amplitude of the electric
field is in the x direction)
c) obtain the Poynting vector

An electromagnetic wave propagates in
the + z direction and travels away from the
source over time. Consider wave function ψas sine wave and ψdescribe an electric
field.
a) In z = 0 and t = 0 the value of the
function ψis equal to -A where A is the
amplitude of wave, in z = (λ)/(2) and t = 0 the
value of the ψis +10. Calculate the
unknown parameters of the wave and
rewrite the wave function
b) Obtain the magnetic field vector
(changes in the amplitude of the electric
field is in the x direction)
c) obtain the Poynting vector
