A linearly polarized electromagnetic wave has an average
intensity of 324 W/m2. This wave is directed towards two
ideal polarizers (in real polarizers, transmission is also effected
by reflection and absorption). Polarizer A is oriented with its
transmission axis at an angle of θ1 = 40.0° with the
incident electric field. Polarizer B has its axis at an angle of
θ2 = 70.6° with the incident electric field, as shown in
the figure.

An electromagnetic wave of intensity is propagated in the air and normally falls upon the surface of a medium of refractive index n. Knowing that the transmitted intensity is 80% of that incident, determine the value of n. Also determine the amplitudes of the electric fields of the incident, reflected and transmitted waves. (Io = 50 W / m2.)

A rectangular loop of wire with sides H = 28 cm and W = 67 cm is located in a region
A rectangular loop of wire with sides H = 28 cm and W = 67 cm is located in a region containing a constant magnetic field B = 1.15 T that is aligned with the positive y-axis as shown. The loop carries current I = 240 mA. The plane of the loop is inclined at an angle θ = 30° with respect to the x-axis. 1) What is ?x, the x-component of the magnetic moment

A plane electromagnetic wave with a time-averaged Poynting vector 〈S!〉 is incident on a long prism made from a conducting material which has a cross-section in the shape of an equilateral triangle, with side length a (see figure below). Assume that the prism is large compared to the wavelength of the electromagnetic wave and that scattering from the corners can be neglected. In other words, it can be assumed that the outgoing waves are produced by specular reflection from the...
