ايه هو الpolarization ؟؟؟؟

[جناب الكومندا المهم]

هو الpolarization عبارة عن ايه

ياريت حد يقول عالسخان كدة

وشكرااااااااا

الاستقطاب بكل بساطة هو توحيد اتجاه الضوء
بمعنى تحويل ضوء مشتت زى ضوء الشمس مثلا الى ضوء زى الليزر كل الاطوال الموجية له موحده الاتجاه ده اللى انا اعرفه ويارب اكون افدتك (ن-1)

The answer of Eng. Van is WRONG, you got the wrong idea but thanks for trying to answer it anyway. The only right thing he stated that natural light is not polarized.

Please post any questions in my questions post.

Polarization is a state of the electromagnetic field that is independent of its wavelength and frequency.

To understand polarization, we think of the electric field as a VECTOR propagating in the x-direction and whose magnitude takes the shape of a sine wave in the y-direction.

When this vector is confined in a single plane in space, this is called linear polarization. When this vector moves so that its tip draws a helix whose cross-section is circular we call this circular polarization.
When the helical path cross-section is an ellipse, it is called elliptic polarization.

To better understand this, think of the electric field as propagating out of the paper towards you and you are looking at it.

If you see the wave coming towards you as a single line, i.e. the wave is fully confined in one plane, then this is linearly polarized light.

If this wave traces a circular path, then it is circular polarized

If it is and elliptical path, then it is elliptically polarized.

شكرا يا فان انك دخلت التوبيك

وشكرا جدا جداااا يا بشمهندس محمد عالتصحيح وعاللينكات

جزاك الله كل خير

اسف انا كنت فاكر ان ده هو الصح من خلال فهمى للمحاضرة
ان شاء الله المرة الجاية هكون اكتر دقة وتكون اجاباتى صحيحة (ن-1)
