Consider electric field of electromagnetic waves that are
parallel to plane of incidence
find
a) fractional ratio of reflected and refracted
fields relative to incident field
b) critical angle at which reflected wave vanishes
Suppose
Magnetic field B = B (z-direction)
Electric field E = E (y-direction)

the energy eigenvalues.
1 a) What is the approximate electric field strength and
magnetic field strength of the electromagnetic waves radiated by a
60-W lightbulb, as measured 5.5 m from the bulb? You can assume
that the bulb is 100% efficient in converting electrical energy to
light energy.
b.) Incandescent light bulbs are very inefficient. Find the
electric field strength and magnetic field strength assuming 5%
efficiency.
Please show all work, thank you!
1. How is the direction of the magnetic field that
accompanies a changing electric field related to the direction of
the changing electric field?
2. What is the main difference between the effects of electric
fields on charged particles and the effects of magnetic fields on
charged particles?
3. What is the relationship between the magntidue of the
electric and magnetic fields for an electromagnetic wave pulse
traveling in vacuum? And how is the direction of B that accompanies
a changing...
In a rectangular waveguide for which a = 1.5 cm, b = 0.8 cm, ? =

A magnetic field with induction B = 15 · 10−4T is
directed perpendicular to the electric field with intensity E = 10V
/cm. The beam of electrons flying at the speed v enters the space
with the mentioned fields. The velocity of the electrons is
perpendicular to the plane containing the vectors E and B.
Calculate: 1) the electron velocity v, if the electron beam does
not deviate under the simultaneous action of both fields; 2) the
