Derive the reflection coefficient and transmission coefficient for the parallel polarization. Hint: Refer the perpendicular polarization.

Determine the reflection coefficient R and the transmission
coefficient T for a vacuum/plasma interface (take the incident wave
on the vacuum side).

Derive the angular spectrum of the field transmitted through
an amplitude grating that the transmission coefficient is T=T0*
cos^2(2pi*x/a). Assuming normal incident plane wave at wavelength
?. Based on the result, design a amplitude grating that has uniform
power distribution into three diffraction orders.

In the Figure, a beam of light, with intensity 43
W/m2 and polarization parallel to a y axis, is
sent into a system of two polarizing sheets with polarizing
directions at angles of θ1 = 70o and
θ2 = 90o to the y axis. What is the
intensity of the light transmitted by the two-sheet system?

whatis the secific meaning for eachone transmission ,reflection and
refraction a diffraction .

Two polarizers are set up so that their polarization directions
are parallel and vertical. Which of the following describes light
that has passed through both filters?
A. The light is polarized in the veritcal direction
B. the light is polarized in the horizontal direction
C. The light is not polarized
D. No light passes through the filters

Using Larmor's formula, explain why there is no reflected light
for the "p" polarization (parallel to the incidence plane) after a
total polarization by reflection in the Brewster angle.

Write equations of the lines through the given point parallel to
and perpendicular to the given line.
4x + 6y = 0, (7/8,3/4)
(a) parallel to the given line
(b) perpendicular to the given line

How can you determine if two lines are parallel, perpendicular,
or neither ?

Polarization Question
(a) Vertically polarized light is incident on a
polaroid sheet with its transmission axis at 45 degrees to the
vertical. What fraction of the incident intensity emerges through
the polaroid sheet? How is this emerging light polarized?
(b) The light emerging from the polaroid sheet in (a)
is now incident on a second polaroid sheet, with its transmission
axis horizontal. What fraction of the intensity incident on the
second sheet emerges? What fraction is this of the original...
