Description: In this Physics video for Class 12 in Hindi we explained how to derive Snell's law for refraction using Huygens principle. We also derived the formula for critical angle. This is a topic of Chapter 10 - 'Wave Optics' from NCERT for Class 12. 👇👇👇👇👇👇 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 0:00 Introduction to refraction and Snell's law 2:34 What is a wavefront? 3:40 What is a plane wavefront? 5:23 Why does refraction happen? 12:35 Derivation of Snell's law using Huygens principle 17:47 Why does wavelength reduce in denser medium? 20:57 Derivation of formula for critical angle
