Polarization

Introduction Sunlight and all other forms of natural light produce vector light waves in the electric field that move in all direct planes relative to the direction of propagation. If the electric field vectors are confined to a single plane using a beam filter by extraordinary means, then all the waves that vibrate in one […]

Before introducing transistors as amplifiers, we need to understand transistors. Transistors are 3 terminal devices which are semiconductors. The following terminals are Emitter as E, base as B and collector as C.  The transistors can act in three different regions like cutoff region, saturation region and the active region.  In this article, we will discuss

According to scientists, light waves are a type of electromagnetic waves. Electric and magnetic fields in light waves are mutually perpendicular to each other and vibrate in planes perpendicular to the direction of propagation of the wave. This happens only if the wave travels in a direction perpendicular to the plane of the paper. If

Introduction Many optical applications require an understanding and manipulation of polarization. It is not uncommon for optical designers to overlook the polarization of light when designing lenses and optical components. Even optical systems without explicit measurement of it are affected by the phenomenon of polarization. A light’s polarization influences its focus, its cutoff wavelength and

The polarisation of light has become an important aspect due to its application in optical fields. Optical design is a subject mainly focusing on the wavelength and the intensity of light while often neglecting polarisation. The latter, however, is an important aspect that affects even optical systems that do not measure it explicitly. The polarisation
