Elliptically Polarized Light

When light is passed through a polarizer, it gets polarized according to the properties of the polarizer.

Considering an extremely Efficient polarizer, The light that emerges out is said to be plane polarized light. The vibration of electric and magnetic vectors is confined to one plane.

When Two Such Plane Polarized Lights Waves, Having Unequal Magnitude And Moving Perpendicular To Each Other, Interfere, They Result Into An Elliptically Polarized Light.

The equation of resultant wave represents that of ellipse.

$\mathbf{E} ( \mathbf{r} , t ) = \mid \mathbf{E} \mid \mathrm{Re} \left \{ |\psi\rangle \exp \left [ i \left ( kz-\omega t \right ) \right ] \right \}$

$\mathbf{B} ( \mathbf{r} , t ) = \hat { \mathbf{z} } \times \mathbf{E} ( \mathbf{r} , t )$

A=|\mathbf {E} |{\sqrt {\frac {1+{\sqrt {1-\sin ^{2}(2\theta )\sin ^{2}\beta }}}{2}}}

B=|\mathbf {E} |{\sqrt {\frac {1-{\sqrt {1-\sin ^{2}(2\theta )\sin ^{2}\beta }}}{2}}}

जेव्हा प्रकाश ध्रुवीकरणातून जातो तेव्हा ध्रुवीकरणाच्या गुणधर्मानुसार त्याचे ध्रुवीकरण होते.

अत्यंत कार्यक्षम ध्रुवीकरण करणारा विचार केल्यास बाहेर पडणारा प्रकाश हा विमानाचे ध्रुवीकरण करणारा प्रकाश आहे असे म्हटले जाते. विद्युत आणि चुंबकीय सदिशांचे स्पंदन एका विमानापुरते मर्यादित असते.

अशा दोन किरणांच्या ध्रुवीकरणझालेल्या प्रकाशलहरी, असमान तीव्रता आणि एकमेकांकडे वळणारे , हस्तक्षेप करतात तेव्हा ते एका एलिप्स ध्रुवीकरणकेलेल्या प्रकाशात रूपांतरित होतात.

What is Solidity programming language?

Solidity is an object-oriented, high-level language for implementing smart contracts. Smart contracts are programs which govern the behaviour of accounts within the Ethereum state. Solidity was influenced by C++, Python and JavaScript and is designed to target the Ethereum Virtual Machine (EVM). Solidity is statically typed, supports inheritance, libraries and complex user-defined types among other features. With Solidity you can create contracts for uses such as voting, crowdfunding, blind auctions, a...

Kuiper belt

I t is a circumstellar disc in the outer Solar System , extending from the orbit of Neptune (at 30 AU ) to approximately 50 AU from the Sun . It is similar to the asteroid belt , but is far larger—20 times as wide and 20 to 200 times as massive. Like the asteroid belt, it consists mainly of small bodies or remnants from when the Solar System formed . While many asteroids are composed primarily of rock and metal, most Kuiper belt objects are composed largely of frozen volatiles (termed "ices"), such as methane , ammonia and water . The Kuiper belt is home to three officially recognized dwarf planets : Pluto , Haumea and Makemake . Some of the Solar System's moons , such as Neptune's Triton and Saturn 's Phoebe , may have originated in the region. The Kuiper belt is distin...

An Oddly Tilted Planet

The rotation period of Uranus’s atmosphere is about 16 hours. Like Jupiter and Saturn, Uranus rotates differentially, so this period depends on the latitude. This can be measured by tracking the motions of clouds. To determine the rotation period for the underlying body of the planet, scientists looked to Uranus’s magnetic field, which is presumably anchored in the planet’s interior, or at least in the deeper and denser layers of its atmosphere. Data from Voyager 2 indicate that Uranus’s internal period of rotation is 17.24 hours. Voyager 2 also confirmed that Uranus’s rotation axis is tilted in a unique and bizarre way. Herschel found the first evidence of this in 1787, when he discovered two moons orbiting Uranus in a plane that is almost perpendicular to the plane of the planet’s orbit around the Sun. Because the large moons of Jupiter and Saturn were known to orbit in the same plane as their planet’s equator and in the same direction as their...
