ध्रुविकरण (तरङ)

रबरको गोलाकार ध्रुविकरण लाइ रेखात्मक ध्रुविकरणमा रुपान्तर गरिएको

ध्रुविकरण (अङ्रेजी:Polarization वा Polarisation) तरङ्गहरूको विशेषता हो जुन एक वा बढी दिशामा घुम्न सक्छ । प्रकाश लगायतका इलेक्ट्रोम्याग्नेटिक तरङमा ध्रुविकरण लागु हुन्छ भने गुरूत्वाकर्षण तरङ हरूमा पनि यो लागु हुन्छ । ग्यास वा तरल का ध्वनि तरङहरू बाट ध्रुविकरण सम्भव छैन किनकि ध्रुविकरण हुने दिशा र तरङको दिशा एकैतिर हुन्छ ।

In an electromagnetic wave, both the electric field and magnetic field are oscillating but in different directions; by convention the "polarization" of light refers to the polarization of the electric field. Light which can be approximated as a plane wave in free space or in an isotropic medium propagates as a transverse wave—both the electric and magnetic fields are perpendicular to the wave's direction of travel. The oscillation of these fields may be in a single direction (linear polarization), or the field may rotate at the optical frequency (circular or elliptical polarization). In that case the direction of the fields' rotation, and thus the specified polarization, may be either clockwise or counter clockwise; this is referred to as the wave's chirality or handedness.
