PPT-UNIT – III Polarization

By Dr P M Patel Introduction Interference and diffraction phenomena proved that light is a wave motion These phenomena are used to find wavelength of light and they do not give any indication regarding the character of waves. brPage 1br 136152ii133152156156136152iii147i 152136152 152vii142i152i152 136152152136133136152ii136152 45GHz dualband omnidirectional directmount indoor AP antenna PO57347IPS57364PU57347JLSSSHY57347PULYMLYLUJL5734757540SLY APPLICATION 133i 135135 136 133136133135iv152i 135152 152136135 136i136152 136152 152i152152 136i i136152i v 136v152136152 i 13615 The value of . reionization. fraction derived from CMB polarization measurements has decreased steadily since WMAP2003 (WMAP2005, WMAP2007, WMAP2011, and Planck 2015). The final word from Planck is not out yet , and whenever it is out, it will surely not be “a 100-sigma measurement” of . Class Activities: . Polarization (1). Class Activities: . Polarization (2). A stationary point charge +Q is near a block of polarization material (a linear dielectric). The net electrostatic force on the block due to the point charge is . in . Interferometry. . Rick .

Different wavelengths have ever so slightly different indices of refraction when passing through materials such as glass, plastic, or water (and probably others).
