Description: In this Physics video for Class 12 in Hindi we explained how polarisation of light happens during scattering and reflection. We also explained the Brewster's angle and the Brewster's law. This is a topic of Chapter 10 - 'Wave Optics' from NCERT for Class 12. Polarized light is light that has its vibration limited to one plane. A light wave that is vibrating in more than one plane is referred to as unpolarized light. Polarisation : It is the process where non-polarized light is converted into polarised light. When unpolarised light is scattered by the molecules present in atmosphere or reflected from the boundary of two media, it gets poarised. Brewster's angle : Brewster's angle (also known as the polarization angle) is an angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection. Brewster's law : When an unpolarized light of known wavelength is incident on a transparent substance surface, it experiences maximum plane polarization at the angle of incidence whose tangent is the refractive index of the substance for the wavelength. 👇👇👇👇👇👇 𝑷𝑳𝑨𝒀𝑳𝑰𝑺𝑻 👇👇👇👇👇👇 🔴 Click here to watch the whole playlist on Chapter 10 : 'Wave Optics' for Class 12 : youtube.com/watch?v=Sagr_3_lOKA&list=PLW0F47OesfFNwxeIPvGc7xBQg89Dvpjpj&index=1 👇👇👇👇👇👇 𝑷𝒓𝒆𝒗𝒊𝒐𝒖𝒔 𝑽𝒊𝒅𝒆𝒐𝒔 👇👇👇👇👇👇 🔴 Wave Optics (Introduction) youtu.be/Sagr_3_lOKA 🔴 Huygens Principle youtu.be/-iz3P4iuNaI 🔴 Refraction using Huygens Principle youtu.be/UZhKHDT08Ow 🔴 Reflection using Huygens Principle youtu.be/NeJRKrTRw6s 🔴 Doppler Effect of Light (Part 1) || RED SHIFT youtu.be/kwpjWv0gJvc 🔴 Doppler Effect of Light (Part 2) || EQUATION DERIVATION youtu.be/ka9q_eXUk5I 🔴 Doppler Effect of Light (Part 3) || Intuition for Frequency Change youtu.be/cytjpgBwVmQ 🔴 INTERFERENCE of Light - YOUNG'S DOUBLE SLIT Experiment youtu.be/Y1bPmdHJuaI 🔴 DIFFRACTION of Light youtu.be/3z0nWghQvlI 🔴 Polarisation (Part 1) || Malus' Law youtu.be/WU7e9fsBwx0 0:00 Interesting demonstration related to polarisation 1:40 What is polarisation (revision) 5:20 Polarisation by Scattering 11:30 Polarisation by Reflection 15:51 Brewster's angle and Brewster's law
