A source emits a beam of light with a wavelength of 525 nm and
an intensity of 500 W/m², the beam falls on a system of three
polarizers where the second and third polarizers form angles of 30°
and 45° respectively with respect to the first polarizer Then the
beam passes through an opening with a width of 0.2 mm forming an
interference pattern on a screen located at a distance of 1.2 m.
Decide:
a) The intensity of the beam after passing through the
polarizer system (6 points). b) The angle and height with
which the first minimum is formed on the screen (6 points).
c) The numerical value of the relationship between the
intensity at the 1.5 mm point with respect to the intensity of the
original source (8 points).
