Polarization is a property applying to transverse waves that specifies the geometrical orientation of the oscillations.
Polarization is a property applying to transverse waves that specifies the geometrical orientation of the oscillations.
13.3.A.2 Transverse waves that are reflected from a surface, refracted through a medium, or pass through specific openings may be polarized.
13.3.A.2.iTransverse waves can be polarized and oscillate in a single plane.
13.3.A.2.iiLongitudinal waves cannot be polarized
13.3.A.3 The polarization of waves may result in a reduction of the wave’s intensity.
13.3.A.3.iIntensity is a measure of the amount of power transferred per unit area.
13.3.A.3.iiThe intensity of a wave is the average power transfer over one period of the wave.
Effect of a polarizer on reflection from mud flats. In the picture on the left, the horizontally oriented polarizer preferentially transmits those reflections; rotating the polarizer by 90° (right) as one would view using polarized sunglasses blocks almost all specularly reflected sunlight.
