Description: In this Physics video for Class 12 in Hindi we derived the mathematical equations for change in frequency and wavelength in the Doppler effect of light for stationary observer. We also explained why positive and negative sign appears in the formulas. This is a topic of Chapter 10 - 'Wave Optics' from NCERT for Class 12. The Doppler effect or Doppler shift is the change in frequency of a wave in relation to an observer who is moving relative to the wave source. It is a very interesting and important topic in astronomy. When the source of light moves away from the observer the wavelength of light increases and the frequency decreases, because, the speed of light for any observer is constant and speed of light is the product of its wavelength and frequency. The mathematical equation for the change in wavelength in non-relativistic Doppler effect is Δλ/λ = v/c. And for the change in frequency in non-relativistic Doppler effect is Δf/f = - v/c. 🔴 Doppler effect (Part 1) : youtu.be/kwpjWv0gJvc 0:00 Introduction to Doppler effect 3:42 Equation for Change in wavelength 6:59 Equation for Change in frequency 👇👇👇👇👇👇 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 👇👇👇👇👇👇 Related videos 👇👇👇👇👇👇 🔴 Doppler Effect in Sound youtu.be/pyya2fRw48Y 🔴 Relativistic Doppler Effect youtu.be/hQVT9HaJLsE 👇👇👇👇👇👇 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 👇👇👇👇👇👇 Next Topics 👇👇👇👇👇👇 🔴 INTERFERENCE of Light - YOUNG'S DOUBLE SLIT Experiment youtu.be/Y1bPmdHJuaI 🔴 DIFFRACTION of Light youtu.be/3z0nWghQvlI
