Can a sound wave be polarized? If not, why not?

The intensity of a particular TV station’s signal is    I =1.01 x 10^(-13) W/m^2 when it arrives at a 28-cm  diameter satellite TV antenna.   A) Calculate the total energy received by the antenna during 5.0 hours and 40 minutes of viewing this station’s programs.   B)What is the amplitude of the field of the EM waves?   (E field)

3. Electromagnetic waves from a radio station pass through an open window of a house. The square window has side length 0.75 m and the waves pass through perpendicular to the window's area. The electric field is measured at the window and found to be 0.02 V/m. In air, we can use the vacuum permeability = 4 x 10-7 H/m. (i) What is the magnitude of the Poynting vector, S, for the radio waves passing through the window? (ii) How much energy do the radio waves carry through the window during a 2-minute-long broadcast of BBC Radio 4's shipping forecast? [Hint: think of the units of S [units = (J/s)/m²] and Energy [units = J].

10. A beam of light polarized along the y axis and moving along the +z axis passes through two polarizing sheets with axes of polarization oriented 30° and 70° measured clockwise from the positive direction of the y axis. The final intensity of the beam is found to be 61 W/m². What is the initial beam intensity? (1) 280 W/m² (2) 700 W/m² (3) 200 W/m² (4) 50 W/m² .2 (5) 140 W/m² 11. Light of wavelength 520 nm is incident perpendicularly on a diffraction grating having 200 lines/mm. What is the highest
